the local singer-songwriter celebrates the release of his new limited-edition vinyl-only album, Unreleased Tracks from the Stage Pass Era. The songs come from the mid-'70s when Koslen played with the late Michael Stanley. For this special show, he'll play songs directly from the album's first side and then participate in a Q&A. For the second part of the show, he'll deliver a live set with his band. The show begins at 7:30 p.m. at the Music Box Supper Club.
