Swarm (1997-2004) is a Thrash Metal band from San Francisco, California, USA.
n 1995, after the death of Death Angel (later The Organization) many of the members disappeared underground only to re-emerge as Swarm to release a four-track self-financed EP Swarm in 1999 with Mark Osegueda (ex-Death Angel; vocals), Rob Cavestany (ex-Death Angel/ex-The Organization; guitar), Michael Isaiah (bass) and Andy Galeon (ex-Death Angel/ex-The Organization; drums). The style was much more diverse than their thrash roots of the past. The Devour EP (2002) came next, with Beyond the End (2004) following it all up by featuring a collection of singles made over the past few years. The band was then put on hold (most likely disbanded) when Death Angel reformed.
