Weedeater is a band that practices what it preaches: the coastal N.C. sludge trio’s live shows can be noisome assaults of sweat, volume and vomit. Southern music, by these guys’ model, can be an unapologetic steamroller of cranked amps and seething grudges. Weedeater swings and boogies, owing as much to Muscle Shoals-descended blues-rock as the obvious swamp-metal touchstones, while wildman bassist and vocalist Dave “Dixie” Collins — who once accidentally shot off his big toe — rants and hollers nihilistic Southernisms in his perennially shredded voice. So, come get some, but bring earplugs and maybe a change of clothes. With Sourvein, Murdercycle, Vulture. $12-$14. Oct. 25, 9 p.m. Tremont Music Hall, 400 W. Tremont Ave. 704-343-9494.
