Mark E. Smith, frontman of the ever-morphing postpunk band The Fall, once bragged that, even if he were to play with your grandmother, that would still be The Fall. In the years since, numerous solo artists have adopted band names, even though they don’t have bands to go with them. Among them are Samuel Beam (better known as Iron & Wine), Conor Oberst (Bright Eyes), Chris Carrabba (Dashboard Confessional) and Justin Vernon (Bon Iver). And then there’s the lesser-known Eric D. Johnson, who has released a half-dozen albums over the two past decades under what he describes as the “dumb fake punk-rock name” Fruit Bats. Or, as his latest official bio puts it: “Eric D. Johnson is Fruit Bats. And Fruit Bats is back.” (Note singular verb.) A former teacher at Chicago’s Old Town School of Folk Music, Johnson has in past lives performed as a member of The Shins and Califone. His solo singer-songwriterly pop inclinations, meanwhile, have often saddled him, not unjustly, with the genre-blurring Americana tag. Judge for yourself at Fruit Bats’ Ivywild School show, which will also feature the nom de plumeless Kittredge, Colorado singer-songwriter Patrick Dethlefs.
