I shouldn’t think too hard about how dumb the musical descriptors “Death Metal” or “IDM” sound, because when it comes to infuriating genre names, it’s the utterance of “folktronica” that’s generally followed for me by an unpleasant little vomit hiccup. Brooklyn’s Ill Lit infuses a little fence-sittin’ Americana with a lot of technology, dances it up with the bedroom lo-fi indie rock of Christmas past, and often gets compared to Grandaddy. But the members of Ill Lit write a more memorable song than their more straightforward contemporaries, a marker that also distances the band from kindred acts currently clogging up the scene with uninspired experimentation. Now a three-piece, the band is also suited for the intimacy a small venue provides. Ill Lit plays with the Shore and Val Emmich at 8:30 p.m. at Iota Club & Cafe, 2832 Wilson Blvd., Arlington. $10.
