Sound Unseen is a film festival for music lovers, featuring a mix of documentaries, biopics, music videos, and events offering an aurally pleasing cinematic experience. The festival kicks off this Tuesday with an opening party at the Walker Art Center, where British-born local singer Katy Vernon will perform, followed by a screening of PJ Harvey’s A Dog Called Money. The documentary chronicles Harvey’s research and travel leading up to her 2016 album, The Hope Six Demolition Project. That event is followed by five more days of screenings, parties, and panel discussions. There will be classics, like Bob Fosse’s All That Jazz; nail biters like Pipe Dreams, which follows five organists as they compete in Canada’s International Organ Competition; and pieces exploring punk music scenes (Punk the Capital, X: The Unheard Music), ska revolutions (Pick It Up! Ska in the Nineties), and legendary stars (Alice Cooper, Michael Hutchence, Gordon Lightfoot). The festival closes out its 20th anniversary with a screening of Boy Howdy: The Story of Creem Magazine, which will include live music from Sick Things, an Alice Cooper/Saint Small tribute band.
