Possibly my favorite LP of all time. As a lover of all musics progressive (of which the well-known prog rock genre is a mere subset), I'm always a pushover for a heavy double LP, the most progressive of all formats (releases with three LPs or more -- box sets and whatnot -- are of course still progressive, but not as progressive as the double LP, because the sheer added volume of the extra material inherently begins to weigh down progress, whereas the double LP is just light enough that progress can continue unabated). This one in particular really hits the spot, on the exotic label Shandar, with an epic rich-colored gatefold sleeve, and on the lovely gold-tinted inside, liner notes handwritten in French and an eerie picture of haunted bald bearded psychedelic music monk Terry lurking at the bottom right, sitting on the floor playing his electric organ through his tape delay machine in full all night flight. As for the music in the grooves themselves, I will say this, Dervishes is the album that basically ruined all other Terry Riley LPs for me. Every time I listen to a different one, no matter how good it is, I'm always thinking, "But I could be listening to Dervishes." It seems to have everything that the other LPs have, all the classic Riley moves, but here so raw, so perfectly distilled. It is the true uncut funk. (It's also a double live LP, and as such stands strong next to all the heavy titans... Alive, Alive II, Live Bootleg, Double Live Gonzo, On Your Feet Or On Your Knees, even Live/Dead, Made in Japan, and Live at the Fillmore East....)
P.S. Oops, forgot the actual reason I made this post, which is to finally make note of a totally killer part that I've always loved but had no idea how to quickly locate because every time I listen to this thing I'm so zoned out that taking notes seems laughable. Well, this time I actually stood up and left the zone to get pencil and paper, so now (you and) I know that it starts right around the 3:25 mark of "Persian Surgery Dervishes Performance One Los Angeles, 18 Avril 1971, Face 2," which is to say the 3:25 mark of side two (and the 24:15 mark of the YouTube above). There are several of these sudden cyclical spiral double helix zone-outs laying in wait throughout this track... something about this particular bassline mantra seems to inspire Mr. Riley into feverishly active tunnels of vision.
