We’re not sure what it is about J.D. Wilkes – maybe it has something to do with his crazy eyes, stringy hillbilly-punk appearance and tendency to replace a horn section with kazoo – but we love to watch this guy put on a show, whether he’s with Southern goth troubadours, the Legendary Shack Shakers, or the more recent rockabilly/ragtime trio, The Dirt Daubers, with wife Jessica and the talented Nashville bassist Mark Robertson. Tomorrow night at Mercy Lounge, you get a double deal with both acts, plus Kansas-based Split Lip Rayfield, who’ve got their own kickass brew of hard-driven, bluegrass-infused Americana. 9 p.m., $14 at the door Dec. 3 if you like you some banjo…
