Fronted by vocalist and rhythm guitarist Kele Okereke, guitar-driven British rockers Bloc Party struck a major chord with Silent Alarm, a 2005 release highlighted by the danceable indie gem “Banquet” and The Smiths-inspired “Like Eating Glass.” A slight departure from the early work that earned them comparisons to post-punk pioneers Gang of Four, the quartet’s aptly titled fourth album Four shows Bloc Party rocking harder than usual after an uncertain period complicated by break-up rumors related to Okereke’s solo projects (which include his debut album The Boxer as well as dance-driven collaborations with Hercules and Love Affair and Martin Solveig). The vaguely political Londoners touch down in Helotes with support from buzz-worthy Canadian electronic outfit Bear Mountain. $23-$28, doors at 6pm Monday, Josabi’s, 17200 Hwy. 16 N, Helotes, (210) 372-9100, josabis.frontgatetickets.com.
