Jens Lekman returns with yet another new acoustic gem, debuting a fourth piece of fresh material possibly slated to appear on his forthcoming LP. “I Don’t Know What To Do With This Information,” a melancholic, jazz-inflected crooner about how “Christmas Eve is hard on the broken family,” was unveiled on BBC Radio yesterday (via TPOE) in a solo live set that included fellow unreleased cut “Cowboy Boots” and An Argument With Myself standout “Waiting for Kirsten.”
