My Bloody Valentine are an alternative rock band formed in Dublin, Ireland in 1984 and predominately based in London. The founding members were guitarist/singer Kevin Shields and drummer Colm O'Ciosoig. The band's lineup during their heyday also included singer-guitarist Bilinda Butcher and bassist Debbie Googe. The band's use of guitar distortion, tremolo, and digital reverb placed them as part of the shoegazing movement. Their 1991 album Loveless took two years to make, but once released it was critically acclaimed. Since Loveless My Bloody Valentine became inactive and Shields scrapped albums worth of follow-up material.
