Poor Jimmy Bosch. This Jersey-born Puerto Rican trombonist and his band’s salsa dura (hard salsa) don’t get anywhere near the ink and online attention given to punk, indie, rap, or free jazz. Sure, his songs usually have Spanish lyrics or are entirely instrumental, but how often do you really find yourself hanging on every couplet yowled at a rock club? And surely no fan of garage rock, sampling, or artsy Chicago sounds can begrudge an interest in musical tradition. And you, with the OutKast double-disc and the New York Noise comp—Bosch’s improvisational, fast-tempoed, brass-driven, conga- and timbale-supported rhythm could just be your next big thing. Bosch and his ensemble play at 8 p.m. at the Rosslyn Spectrum, 1611 N. Kent St., Arlington. $28. (703) 228-1850. (Steve Kiviat)
