When the LA band Fishbone came along in 1985, it was impossible to classify, a wildly energetic crew of African-American punks whose sound incorporated ska, metal, funk, and soul. This 2010 documentary often recalls Anvil! The Story of Anvil in its questionable objectivity, both recording and participating in the band’s quest for a comeback. Even as a hagiography, though, it’s pretty interesting: Fishbone predated—and outlived—the early 90s “alternative” boom that provided it with a brief marketing hook, yet the band truly embodied alternative music’s underground ideal, challenging listeners of all races and musical persuasions. Documentary makers Lev Anderson and Chris Metzler follow the band’s current line-up of players as they slog through a modest club tour of Europe, and the fact that they should have been huge 20 years ago only intensifies the sting of their reduced circumstances now.
