Since the old, 2CD DG recording of this piece is not available, this is the only choice. "Drumming" is a very fine work by Reich, more rigorous and less immediately lovely than "Music for 18 Musicians," but rewarding nonetheless. It's an important transition piece between his early work and "18." The first section is literally all drumming, and builds through an arch structure using Reich's technique of rhytmic patterns moving in and out of phase. The following sections add tuned percusion, e.g. marimbas, and move towards his newer style of more harmonic richness, with chords gradually building, shifting, conflicting and moving to new tonal centers. Obviously, if Reich's style of Minimalism doesn't appeal, you won't like this CD. But if you enjoy his other work, this will be a great addition to your collection.
