Seminal British post-punk band Gang of Four is currently in the midst of a worldwide tour, and it stopped in Chicago recently to play music from its most recent release, Content. Though now playing without original bassist Dave Allen and drummer Hugo Burnham, the Gang is still ripping through its classics with new members Thomas McNeice and Mark Heaney, respectively. Photographer Tracy Graham captured these shots of the band, rocking as if no time had passed at all since its last album of new material, Shrinkwrapped, in 1995.
