Hybrids of jazz and what passes for “classical” music these days can be deeper and darker than Gershwin’s Rhapsody in Blue or Wynton Marsalis’ PBS music-ed classes. Austin’s Golden Arm Trio not only finds those spaces but explores them with a restless energy. Headed up by bandleader/composer Graham Reynolds, the group features a revolving cast of musicians—the “trio,” it seems, isn’t actually a trio. The Golden Arm project has produced two CDs and a variety of collaborations with choreographers and filmmakers. Joining them for a performance tonight at the Museum of Contemporary Art is the Fending/Matis Duo, a collaboration between guitarist Jonathan Matis and percussionist Brian Fending of D.C.’s own improvisation group Gray Code. The press release promises that Fending and Matis will, among other things, present a “catalog of sounds” that will “create a Rothko-like texture.” For those about to art-rock, we salute you! At 8 p.m. at the Museum of Contemporary Art, 1054 31st St. NW. $10. (202) 342-6230. (Richard Byrne)
