Interstellar Blue, the forthcoming EP from Purling Hiss, is set to arrive on July 9 via Drag City. Mike Polizze and friends recently shared its lead single, “Useful Information,” an even-keeled, psych-blues sojourn. The track takes you on a languid, muggy stroll in the summer sun, as a bit of guitar-fueled heat blares down upon you. Purling Hiss will be performing next in Philly on Thursday, July 11, with support from Writhing Squares and Long Hots.
