Beginning today, 27 April, another Book of the Week abridgement – and, following on from December’s Schubert-themed series, another book about music and musicians. This time, the unique master of minimalism, Philip Glass. It’s a big, wide-ranging book, part memoir, part social history, part musical theory. It ranges from New York to Paris and the sub-continent; from David Bowie to Mahatma Ghandi. Though, for Bowie worshippers, that isn’t very far at all.
