Cattle Decapitation
Cattle Decapitation is a band from San Diego, California. The band plays death metal to grindcore, which is very sharp in the group's performance. The band's lyrics are oriented against animal suffering and in support of the Earth and the environment. In the beginning, all the members of the band were vegetarians, now only half (John Elmore and Travis Ryan).
