Singer-Songwriter-Producer Josh Joplin has transformed the boundaries of indie-rock into confessional territory. He’ll be celebrating the 2001 release of Useful Music—producedby Jerry Harrison of Talking Heads—as well as performing selections from his five other albums on a solo tour that will land him in Hillsborough March 18, and also in Montclair March 21 (with Jeffrey Gaines) at Outpost In The Burbs.
