The Philip Glass Ensemble formed in 1968 and performed in lofts, museums, art galleries and, eventually, concert halls. Two of Glass's early pieces - the long form Music In Twelve Parts and the opera Einstein on the Beach - secured his reputation as a leading voice in new music.

But America's soon-to-be most successful contemporary composer continued to earn a living by driving a taxi until he was 42. "I would show up around 3pm to get a car and hopefully be out driving by 4. I wanted to get back to the garage by 1 or 2am before the bars closed, as that wasn't a good time to be driving. I'd come home and write music until 6 in the morning."

Glass's new musical language - consisting of driving rhythms, gradually evolving repetitive patterns and amplified voice, organs and saxophones - reflected the urgency of the city surrounding him. New York, on the brink of financial collapse, was crime-ridden and perilous. Driving a cab offered more than a window on this gritty, late night world. Almost every other month, according to Glass, a driver colleague was murdered. Glass escaped altercations with gangs and robbers in his cab.
