check out Rockers, the 1979 Jamaican film about life as a reggae musician. released right about the same time young british punks were introducing reggae as an influence in their music.
also, It Came From Detroit, a documentary about the early 2000’s garage rock ‘revival’ and it’s effects on the Detroit rock scene. features probably my favorite band of all time, the Dirtbombs. i wonder if it’ll get a release in Australia?
