To be musically avant-garde in the 1950s meant to be difficult. Not by the end of the 1960s. That decade saw a group of American beatniks overthrow the musical givens of postwar Europe. In a series of disobediently straightforward compositions La Monte Young, Terry Jennings, Terry Riley, Steve Reich and Philip Glass declared that music could be clear, honest, pretty and experimental. Turning their backs on the conventional centres of musical power, the earliest minimalist works got their first public audience in La Monte Young's 1960-61 Chamber Street Series in Yoko Ono's New York loft. Through the 1960s in art galleries and alternative spaces, the minimalists slowly demystified, democratised and Americanised European modernism. They rejected the angst (what Philip Glass would call "crazy creepy music"). They rejected the invisible games. They rejected the theatricality. "I don't know any secrets of structure that you can't hear," wrote Steve Reich in his 1968 minimalist manifesto, Music as a Gradual Process. Minimalism claimed that there was enough interest in the sounding process itself and enough new territory to be explored in rhythmic patterning to sustain a work. If one removed the Baroque complications - the harmonic story-telling and thematic cleverness - that were obscuring the natural beauties of rhythm and sound, what would be revealed and discovered could provide classical music with a new lease of life. They were right. Minimalism was the last great musical revolution of the 20th century. And it became the most influential and successful ism of them all. In the spirit of the loft concerts we also present new works by David Chalmin, Raphael Seguinier.
