This piece, featuiring variable instrumentation, is part of Philip Glass's earlier experiments in minimalsism and stasis. However, unlike previous works of static repetition, this piece gradually adds new instruments as the music progresses. The significance of each entry causes a remarkable change in the music that lifts the minimalist approach to a higher level of energy and drama.
