You know the one thing every musician has in common? They all think they’re defying genre (even when they’re derivative as hell). For years, four-piece Maryland band Clutch felt miscast as nu metal, stoner rock, post-hardcore and so on. And so the band responded last March by churning out its 10th studio album, “Earth Rocker,” a straightforward up-tempo rock ‘n’ roll effort that’s gotten mostly positive reviews. The straightforward rockers/nu metalers/whatever you want to call them take the stage with Austin heavy metal band The Sword and Pennsylvania rock band Crobot. Labels aside, Clutch packs a punch live, so be ready. 7 p.m. Jan. 5 at Freebird Live, Jax Beach, $25.
