Music in Twelve Parts, written by Philip Glass between 1971 and 1974, is a deliberate, encyclopedic compendium of some techniques of repetition the composer had been evolving since the mid 1960s. It holds an important place in Glass's repertory - not only from a historical vantage point (as the longest and most ambitious concert piece for the Philip Glass Ensemble) but from a purely aesthetic standard as well, because Music in Twelve Parts is both a massive theoretical exercise and a deeply engrossing work of art. Very rare. Only one copy available.
