Tonight and tomorrow at Santos the O.T.O.'s throwing a festival of experimental musicks by practicing magickians, the first one of its kind. No one on the bill is a member of the O.T.O. though, so this isn't some kind of recruiting gimmick--you really think they'd do that? No, it was put together in a more general way to explore the impact of Thelemic culture on music and art, and maybe to make sure no one mispronounces Crowley's name again, thanks to Ozzy Osbourne. Tonight's performers at the Musicka Mystica Maxima (check out the site--it's just as cryptic and bare-bones as you'd think it would be) are Genesis P-Orridge & Thee Majesty, Amber Asylum, Arrington de Dionyso, Larkin Grimm, and Nautical Almanac. Between each set there'll also be live ritual action performances including an invocation from Crowley's Gnostic Mass and Crowley's "Hymn To Pan," which is totally worth going to alone, especially if you're into veils and swords and salt.
