TERRY RILEY

*Reed Streams (1966 Mass. Art recording;O.P.).

* In C (Col. MS-7178). The classic Minimalist piece. The liner notes of this late 60s recording are charmingly dated, but the music's still a "trip," as the notes say; you can still "dig it" twenty-odd years later.

*Rainbow in Curved Air, Poppy Nogood and His Phantom Band (Col. MS-7315), By 1969, Riley's solo style had essentially matured. Rich textures from solo keyboard or sax plus "time-lag accumulator."

*"Rainbow in Curved Air" from the LP Katrina Krimsky (Transonic 3008) NMDS. Krimsky's reading of the work is excellent, though it's only seven minutes long. She uses multitracked pianos to create some interesting effects.

* Persian Surgery Dervishes (Shandar 83.501/502, 2 LPs). Electronic organ and tape delay. One of several collections recorded in Europe in the 70s and used in one film or another.

* La Secret de al Vie: Lifespan (STIP ST-1011). hard-to-find soundtrack material; organ and delay.

* Descending Moonshine Dervishes (Kuckuck 047) CH. Concert recording from Berlin's 1975 Metamusik Festival. A trancelike work for organ with stereo two-channel output and delay.

*Shri Camel (CBS M-35164). The last of Riley's solo organ discs. Four shorter works, using a versatile electronic delay system. One of his most exotic, mystical, and effective albums.

* Songs for the Ten Voices of the Two Prophets (Kuckuck 0647) CH. Indian-style vocals and two Prophet-V synthesizers. The vocals may take some getting used to, but the combination is truly enchanting. Side one's "Embroidery" is a terrific piece; the singing on side two is less assured, but this LP is still capable of some real surprises.

* Cadenza on the Night Plain and Other String Quartets (kronos Qt./Gram. 18 7014-4) GRAM. The ubiquitous Kronos turns in precise performances; the music has the same other-worldly aura as Riley's keyboard music, though the string quartets are not as immediately colorful.This is a two-record set of very subtle beauty; it may take several hearings for the full impact of the music to be felt. The title work has thirteen movements, drawing on folk, classical, and raga styles.

* No Man's Land (Plainisphere PL 1267-17) NMDS. A film score, with Riley playing piano or synthesizer, and Indian musician Krishna Bhatt playing sitar and tabla. These short works are some of Riley's most energetic, and often seem to use jazz elements.
