This evening’s Tuesday Tune-Out, curated by WKDU‘s Yoni Kroll, will be a tribute to troubadour and left-wing activist Billy Bragg. There will performances of his music by Josh Alvarez (Cinepunx), Colin Smith (Serpent Throne), and Carly M (No Other). As always, there will be a mystery screening of a film, which isn’t much of a mystery tonight. You’ll be treated to a rare concert film, Billy Goes to Moscow, that documents Bragg’s 1988 tour. Come join in and singa-long! PhilaMOCA, 531 N. 12th St., 8pm, $5 Donation, All Ages – H.M. Kauffman
