Glass, P: In the Upper Room

“Slightly over half the dances which Glass wrote for choreographer Twyla Tharp's In the UpperRoom in 1986 were issued by CBS a year later under the title Dance Pieces, but this disc presents the complete cycle for the first time.
Comparing the two recordings makes for an interesting exercise in minimalist performance practice. When Dance Pieces was released, the trend was towards layering electronically manipulated and treated sounds over acoustic instruments to impart a more polished sheen to Glass's music. The result was clinical and, one suspects, driven at the time by corporate pressures to make the music as commercial as possible.
Twenty years later, and Glass has decided to revisit the original masters in order to try to recapture the live sound which accompanied the original ballet production.
There is certainly more warmth and depth here, with the ebullient, processional Dance IX benefiting in particular from a more three-dimensional sonic facelift. At the same time the reinstated dances do little to supplement any perceived deficit in the abridged version, or the need to restore some kind of cyclic unity to the work. The disc's highlight, Dance VIII, with its haunting, fragile piano figure is already present in the original version, as are most of the weightier, more extended movements. The 'missing' dances are on the whole short and somewhat transitional in nature. All this adds further weight to the fact that there were sound reasons for leaving them out in the first place, although Glass aficionados will no doubt be glad to receive the complete set.” Gramophone Classical Music Guide, 2010
