South America: a continent of impossible geography. Vast rainforests, the driest deserts on Earth, coastlines stretching for thousands of miles along two oceans, and the world’s longest continental mountain range. Running through it all like a spine of stone and snow: the Andes.
Tonight, we’ll allow the music of this continent to tell its particular story. Unlike previous episodes, the journey we invite you to take with us won’t be a direct trip from country to country. Instead, I hope it captures the very soul of South America: layered, complex, nuanced, rooted in the earth, defined by history, and joyous in celebrating its people.
South America is a region where geography and politics have always been entwined. Military dictatorships, disappearances, revolutions and exile; censorship and resistance. Within this context, progressive rock quickly evolved its own styles and sounds. It was adapted, subverted, and made to speak in local musical and political languages.
We begin where so much of its music begins: in the landscape itself.
Part One: Landscape and Identity
The Andean Spine – Chile, Peru, Bolivia
Bauda are a Chilean band who draw their inspiration directly from the landscape around them. Their music doesn’t just reference Chile’s mountains and valleys; it captures and inhabits them. Vast, majestic, awe-inspiring, unhurried. The music could only have been made here, in this place, on this soil, breathing this air.
“Ghosts of Phantalassa” is nine minutes of Chilean landscape rendered in sound. As you listen, I invite you to let the music do exactly what it sets out to do: take you somewhere. Somewhere high, somewhere ancient, somewhere the wind has been blowing longer than any of us can imagine.

Chile
The Andes don’t recognise borders. The spine of stone, rock, and snow running through Chile continues north into Bolivia and Peru. The same mountains, the same ancient winds, the same indigenous traditions capturing their heritage in music and song long before the first electric guitar was ever plugged in.
Flor de Loto are a band who celebrate both their geographical as well as their cultural inheritance. Their use of the quena flute, the charango, and the rhythms of the altiplano isn’t decorative. They are the music. Progressive rock becomes the channel through which something much older speaks: a modern form expressing an ancient identity.
On their 2025 album Cosmos, they invited Fates Warning vocalist Ray Alder to join them on “Crossfire” – a collaboration that speaks to an important aspect of contemporary South American prog: locally grounded, globally connected.

Peru
Our journey along the Andes continues with our next band. However, we’re going to listen to something a little different and travel back in time.
Bolivia sits at the heart of South America. One of the highest countries on our planet, it is landlocked and mountainous. Yet it also encompasses the Atacama Desert, the Amazon Basin rainforest, and Lake Titicaca. Its capital, La Paz, sits more than 3,600 metres above sea level, in the shadow of a mountain which has watched over this city for millennia. That mountain is Illimani.
Wara were a Bolivian band active in the 1970s. They formed as progressive rock was emerging and slowly finding its feet across the continent. What made them distinctive was the same musical instincts and sensibilities we’ve already heard in Bauda and Flor de Loto: an insistence on rooting the music in the landscape and indigenous traditions of their homeland. If you like, they created a form of heavy prog with Andean DNA, where ancient rhythms meet electric guitars.
Their track “Illimani” takes its name from the sacred mountain above La Paz. As you listen, keep in mind what we’ve already heard; there are direct connections, echoes, and whispers of the same voice expressed in a different style. I feel an immediate sense of how the music of these mountains, passed like a torch across borders and generations, helped to shape what South American prog would become.

Part Two: Soil and Blood
Resistance and Opposition – Brazil, Uruguay, Argentina
The mountains have spoken. The story has begun. Now the land itself has something to say.
In the 1960s and 1970s, South America was facing enormous pressure. In Brazil, Argentina, Uruguay, Chile and beyond, military dictatorships tightened their grip. Censorship was a key method of control. Dissent was dangerous, if not terminal. Yet, amid all this unrest and repression, something exceptional happened: musicians found ways to give the people a voice through sound. Resistance through rhythm. Saying the unsayable through music.
In Brazil, this impulse found its most vivid, challenging and subversive expressions in a cultural movement known as Tropicália. The music and the lyrics were irreverent, psychedelic, and nearly always politically charged. Tropicália fused Brazilian folk traditions with rock and roll, avant-garde experimentation, and a fierce, joyful refusal to be silenced. At the centre of this outpouring was a band called Os Mutantes.
Their name means “The Mutants.” They evolved and mutated, absorbing influences from everything around them and transforming them into something distinctively, defiantly Brazilian. “A Minha Menina”, which translates as “My Girl”, might sound like a simple love song. But listen a little more carefully. A gleeful, coded subversion runs through it; joy deployed as an act of resistance.
♪ Os Mutantes – A Minha Menina
Brazil
In 1973, a military coup ended decades of democratic tradition in a country once known as the “Switzerland of South America.” Uruguay was a model of progressive politics and, more importantly, of stability in a turbulent region. What followed was twelve years of military rule, characterised by systematic repression, torture, and the imprisonment of a higher proportion of its population than in almost any other country on Earth.
It is incredible, even astounding, that in this difficult climate, a band called Psiglo emerged and created such beautifully captivating music. It would have been easy (and safer) to make escapist music. But the band looked the situation directly in the eye. Their album Ideación emerged during a period of deep national trauma, and the track we’re about to hear could not be more explicit in its intent: “Piensa y Lucha”. Think and Fight.
Two words. A manifesto. In a country where thinking freely was an act of courage and fighting back was an act of survival, Psiglo said both out loud. Progressive rock as an act of bearing witness. Of refusing to look away. Of living the reality of people’s lives.
♪ Psiglo – Piensa y Lucha
Uruguay
Uruguay and Argentina share more than a river. Throughout the 1970s, they shared a dark, deep history.
Argentina’s military dictatorship, which began in 1976, would become one of the most brutal on the continent. The Dirty War. The estimate is in excess of thirty thousand people disappeared. And yet Argentine cultures resisted being extinguished. Writers, filmmakers and musicians found ways to keep the voice of the people alive. They created in code; they created in exile, but always under the threat of enormous personal risk.
Crucis were an Argentine band active in the mid-1970s, just as this darkness was descending. Their music is symphonic progressive rock: complex, ambitious, deeply serious. They weren’t as explicit or obvious as Psiglo; they didn’t wear their politics on their sleeve. Listen for the weight, the gravitas of their music. This is music which refuses to be trivial. It carries the burden of life under a regime, and because of this, becomes an intense form of resistance. It insists beauty matters, and nuance are creative forces where the human spirit cannot be reduced or defeated.
In a country where words could cost you your life, lyrics were marginally safer than slogans.
Their track “Determinados Espejos”, which translates as “Certain Mirrors”, appears on their debut album. Listen attentively. This is music reflecting something back at you. Something worth seeing. Something worth feeling.

Part Three: The Sound in Full Flower
Brazil, Argentina, Colombia, Chile
History never disappears. The darkness doesn’t lift all at once. It recedes slowly, and what grows in its wake must always carry the memory of what came before.
We return to Brazil. But this is a different Brazil from the one we visited earlier. From the streets and the carnival energy of Tropicália, we find ourselves moving to the concert hall. The conservatoire. This is a Brazil looking to Europe, to classical music and asking: what happens if we make this our own?
The band Bacamarte were one of the answers to that question. Active since the late 1970s, their symphonic progressive rock is highly orchestral and architecturally ambitious. They created music built around movements, expressed with the discipline of classical styles, yet unmistakably Brazilian in its fire and passion.
Their track “Depois do Fim”, which translates as “After the End”, feels exactly like it’s the right place for us to be now. After everything we’ve heard. After everything we’ve felt. The sun rises, and hope emerges, once more.

Brazil
Bacamarte transformed what classical music could be in Brazil. Fifty years later, Fleesh are now taking the question further: what does progressive rock sound like in Brazil today?
The answer? It becomes something intensely, intimately personal. Fleesh are a duo: Gabby Vessoni and Celo Oliveira, based in São Paulo. I suspect many of you already know them for their extraordinary cover recordings: faithful, joyous recreations of classic prog albums. But the covers are only part of the story. When Fleesh write their own music, something else emerges which is breathtaking.
Their 2024 album Dreamension is remarkable. Atmospheric, cinematic, emotionally layered, and oozing passion, sensuousness and energy. This is music which is enticing; alluring, inviting. It draws you in, slowly, seductively, and then holds you there in its warm embrace.
“Underwater” is the track we’re going to listen to. The title has many resonances. Present-day Brazil is a wonderful cosmopolitan country emerging from a history of struggle and hard-won freedoms. The music is introspective, exploring private experiences with the same care and meticulousness as earlier generations mapped the political ones.
From the concert halls of the 1970s to the studios of contemporary São Paulo, Fleesh capture Brazil’s progressive journey, still unfolding, still deepening, and still relishing what the future may hold and what it might become.

From Brazil, we return to Argentina. Two neighbouring giants of South American prog, each with a distinctive voice and its own relationship to the music and the circumstances which shaped it.
Argentina’s progressive story evolves, deepens, and finds new voices to carry the symphonic tradition forward.
Nexus are one of those voices. Based in Buenos Aires, they firmly sit within the symphonic progressive rock tradition: elaborate, melodic, emotionally ambitious. Their 2019 album Metanoia has stayed with me since I first encountered it. Metanoia is Greek for a fundamental change of heart or mind. A transformation.
“Tiempo sin Razón”, which translates as “Time Without Reason”, is the track we’re going to listen to. I’ve chosen it because, again, there is something in the title and in the music which echoes across everything we’ve heard in this show: voices which persist, a people who are resilient, and a refusal to abandon hope in the face of the unreasonable, the ugly and the unbearable.
Listen for the way the music slowly builds. It is patient, inevitable, a whisper, something which has been lingering, waiting for a long time to be heard.
The music of Argentina isn’t only about what has been endured. The sheer beauty of modern South American prog lies in its message about what can still be and what is yet to come. In a region that has lived through so much, forming a band and creating intricate, hopeful, forward-looking music is something that can only make you shake your head. It tells us the future is still open; transformation is, and always will be, possible. The music we hear is a promise, a commitment, to what is yet to come.

From Argentina, we travel to Colombia. South American prog doesn’t stop at the borders we’ve already visited: our journey continues, uncovering new voices and stories.
Argovia are a Colombian band who came to my attention recently and immediately demanded a place in this show. Their latest album, Primal Repetition, is ambitious and encompassing, yet edgy and distinctly modern. On the track we’re about to hear, they invited Ross Jennings, vocalist with the British prog band Haken, to join them.
The track is called “Ebb and Flow.” If you think about it, there are no two better words to capture the flavour of the journey we have taken together. The push and pull of history, of resistance and persistence, of darkness and light. Locally rooted. And now globally connected.

We began in Chile, with mountains, landscapes, and the atmospheric world of Bauda. And now, as we come to the end of our time together, we return.
Chile has given progressive rock some of its most distinctive and internationally celebrated voices. Aisles are perhaps the finest example. Their music is cinematic, sweeping, and emotional, yet precisely crafted. It captures the spirit of South American life, telling stories without words.
Their album 4:45 refers to a specific moment in time. The precision of naming the time speaks to everything we’ve heard tonight. History is made of moments. Music captures them. And sometimes, by capturing them, music makes them last forever.
As we listen to 4:45, please reflect on the journey we’ve taken together. The mountains, the deserts, the forests and the winds. The resistance, the uprisings, the endurance, the will to carry on. The darkness and what is now growing in its wake. The promise of what is still to come.
South America has given the world progressive rock that is, without doubt, uniquely, defiantly, and beautifully its own. Tonight, we’ve heard only a fraction of it. I hope it has moved you. I hope it has surprised you. Above all, I hope it has made you want to hear more.
