World Under Blood is an American melodic death metal band from Los Angeles, California.Formed in 2006, the band originally featured vocalist and guitarist Deron Miller and drummer Tim Yeung, with bassist Risha Eryavac and guitarist Luke Jaeger completing the four-piece lineup in 2007.The group released its debut album Tactical in July 2011, which featured contributions from guitarist James Murphy. Following the release of the album, Eryavac and Yeung left World Under Blood, to be replaced by current bassist and drummer Kyle Konkiel and Mike Heller, respectively.However, since 2012 the band has remained largely inactive, due in part to Miller's return to focus on his other bands, CKY and Foreign Objects, as well as the busy schedules of other band members.
