South by Due East, Guy Schwartz and Marlo Blue’s annual free music festival, returns this Friday starting at 5 p.m. at Last Concert Café. A three-day event featuring a ton of local Houston bands from many different musical genres performing on two stages, SXDE is a good way to see and hear a lot of Bayou City talent together in one spot and save some bucks on cover charges while you’re at it. You’ll likely discover some bands you’ll want to go see again and support in the future, of course.
