Joe Cole (April 4, 1961 - December 19, 1991) was a roadie for Black Flag and Rollins Band. He was also a very close friend of the musician/author Henry Rollins. He released a book on 2.13.61 publishing, Planet Joe, in which he documented his experiences on the last Black Flag tour and first Rollins Band tour. He was shot and killed in a robbery at Rollins' home on December 19, 1991. Sonic Youth's "100%" was inspired by Cole's murder.
