|In The Upper Room is a collaboration between choreographer Twyla Tharp and composer Philip Glass. This new disc marks the first complete recording of the 1986 ballet. The first recording of the work, released on Sony's Dance Pieces, presented only five of the work's nine movements. Also, Sony's disc heavily reinforced the acoustic instruments with synthesized tracks, presumably to artificially thicken the orchestral sound. This new, definitive recording uses only acoustic instruments, as the composer originally intended.
