Formed in 1987 by bassist and vocalist Glen Benton and drummer Steve Asheim, the Florida group embodies the musical and lyrical morbidity of a music that deals solely in volatile extremes. The group splattered into mainstream consciousness in 1992 with the release of its second album, “Legion,” and has continued to spread its disease ever since with a gruesome succession of albums, tours and controversies.
