Though it never really went out of style, the saxophone trio (sax, bass, drums) has seen a renaissance in the past five-or-so years. That doesn’t mean that Bishop/Cleaver/Flood is just one of a multitude, however. It might not even be fair to call the group a saxophone trio, since you’re as likely to hear drummer Gerald Cleaver, a nearly unmatched virtuoso, dominate the proceedings as saxophonist Andrew Bishop or mesmerizing, unflappable bassist Tim Flood. In other words, no leader exists in the sense of either personality or instrument. This combustible combination of equals stands committed to variety and creative liberation, yet there’s a remarkable accessibility in its sound, so beholden to groove and melody that no passing familiarity with jazz is required to sink your teeth into it. Your run-of-the-mill saxophone trios can’t always pull that off. Bishop/Cleaver/Flood performs at 8 p.m. at Atlas Performing Arts Center, 1333 H St. NE. $22–$28. (202) 399-7993. atlasarts.org.
