Philip Glass, Steve Reich and John Adams are America's greatest living composers. Between them, they have helped change the way music is made and heard, repeating rhythms, highlighting melodies and overlapping time signatures to create new musical languages that are widely heard in the looped and sampled soundtrack to the 21st century. As they reach milestone birthdays, they talk to John Wilson about their work, and about the musical movement that links the three of them - Minimalism.
