UFO or Die originally started life as Hasty Snail Baby, and consisted of Yamatsuka Eye, Yoshimi P-We (pre-Boredoms), and Yoshikawa. Eye started the project so he could play guitar, but later replaced it with a sampler. Yoshikawa quit and was replaced by Katsumi, the bassist for Omoide Hatoba, so the name was changed. Katsumi quit and was replaced by Leningrad Blues Machine bassist Naoto Hayashi. The band is currently on hiatus. Read more on Last.fm
