If speed really does kill, please, don’t tell Busdriver. The L.A. “Art Rap” MC rhymes so quickly sometimes, you wonder if he has a Silly Putty tongue. Of course, the number of syllables one can spit in a micro-millisecond has nothing to do with lyrical ability (cough, cough — Twista), but Busdriver is cool in that department as well, unraveling whip-snaps of slanted, clever, surrealistic and funny couplets (he doesn’t always do the hyper-rhyming). Busdriver’s actual flow is percussive and unpredictable, bobbing and weaving between and with the grooves. The former Anticon-affiliated MC’s latest album, Jhelli Beam (on hip label Anti-), is being celebrated by many major press outlets for its weirdness. Jhelli Beam is a twisted, jerky exhibition of funhouse Psychedelic Rap that sounds like a Red Bull-and-trucker-speed-fueled party at the old long-closed amusement park where Andre3000 and the ghost of Ol’ Dirty Bastard are the guests of honor. Why wouldn’t you want to be there when Busdriver (and fellow L.A. MC, Abstract Rude) performs at Northside Tavern Wednesday. Need the deal sweetened? Remember, as always, shows at the Tavern are free. 10 p.m.
