In C and Rainbow in Curved Air get all the ink (inc?), but its own somewhat subtle way, 1980’s Shri Camel, the last of the three brilliant albums Terry Riley recorded for CBS, is every bit as groundbreaking as its hallowed predecessors. Not content to rest on his laurels as a minimalist master, Riley studied with Hindustani classical singer Pandit Pran Nath during the ‘70s; by blending that Eastern influence with his own experiments in just intonation (where tuning is dictated by equal mathematical intervals rather than the “tempered” tuning familiar to Western music), Riley made an album whose shimmering textures (played through a specially modified Yamaha organ) seem to change with one’s own breath or thought, like the reflection of rippling water on rock. And while Shri Camel is far more demanding and ultimately rewarding than any “New Age” recording, one definitely gets the sense that its ever-evolving, ecstatically hypnotic rhythmic and harmonic patterns are massaging the brain’s neural circuitry, leaving one refreshed, relaxed, and, yes, maybe even a little smarter than before listening. First LP reissue and long overdue!
