For those wolves and wolf-sympathizers, there will be much howling at the moon in honor of Guitar Wolf bassist Billy. Billy died of a heart attack in Tokyo yesterday. Guitar Wolf, a Japanese punk-rock trio known for exclusively wearing leather and claiming to be descended from actual wolves, just wrapped up a North American tour. The band formed in the late ’80s and drew an American audience when Missile Me! was released on Matador Records in 1996. Bass Wolf Billy is survived by Guitar Wolf Seiji and Drum Wolf Toru.
