Philadelphia's Relache Ensemble - lives by a credo: "music unbound." This gives its modern minimalism breathing room for inventive experimentalists such as vocalist-composer Kitty Brazelton Ñ known to locals from her Swarthmore-student '7Os with Musica Orbis. Brazelton's music (from the sounds of her teaming with Dadadah for Love Not Love Lust Not Lust) is a cabaret of white-hot guitars, reed sounds, holiday brass, tiltawhirl pianos, and dreamy, Stravinskyesque strings. Though it's unfair to compare Brazelton's rapturous sing-soaring to screecher Diamanda Galas or Philly's own mistress of multiphonics, Joan LaBarbara, there is indeed a relation to both divas. Expect the union of Relache and Brazelton to touch on the tragedy of Sept.11.
