Punk's raw power rejuvenated rock, but by the summer of 1977 the movement had become a parody of itself. Rip It Up and Start Again is a celebration of what happened next - postpunk bands like PiL, Joy Division, Gang of Four, Talking Heads, The Fall and Cabaret Voltaire, who dedicated themselves to fulfilling punk's unfinished musical revolution. The postpunk groups were fervent modernists. Experimenting with electronics and machine rhythm or adapting ideas from dub reggae and disco, they were totally confident they could invent a whole new future for music.
