Launched in 1999, Minneapolis-founded music and film festival Sound Unseen celebrates a quarter century locally with three days of documentaries about trailblazing artists. On Day 1, Linda Perry: Let It Die Here celebrates the decade-spanning rock and pop hitmaker, while Bastards of Soul uncovers the story of the tragedy-struck Texan band on Day 2. Saturday wraps with the conference’s usual ATX short film showcase, plus two more rock docs: Takin’ Care of Business, about songwriter Randy Bachman, and Bloody & Bruised: The Untold Story of the Back Room, the notorious East Riverside club. – Carys AndersonDec. 12-14
