UFO or Die (also known as Unlimited Freak Out Or Die) is a side project of two Boredoms members Yamatsuka Eye (vocals, sounds) and Yoshimmy P-We (drums). The bassist player in the band changed a few times, with Yoshikawa eventually replaced by Naoto Hayashi. Eye started the band so he could play on guitar, but later he gave it up for a sampler. UFO or Die released their first single U.O.D. in 1992, followed by the 7-inch on Skin Graft two years later. In the same period, the group recorded material for their debut album Cassettetape Superstar, released on CD and LP in 1996. While never officially disbanded, UFO or Die has been on a long hiatus since the middle of the 90s.
