Vengeance Rising was an American Christian thrash metal band from Los Angeles, CA. Fronted by vocalist Roger Martinez, they originally formed as Vengeance in 1987, but changed their name in 1989 to avoid conflict with another band from the Netherlands. Band members Larry Farkas, Doug Thieme, Roger Dale Martin, and Glenn Mancaruso left following Once Dead and formed the band Die Happy. Roger Martinez stayed on to record two more studio albums, but aside from him, Vengeance Rising's lineup changed for each subsequent album. While the group was a ground breaking Christian metal band, today Vengeance Rising is known for vocalist Martinez' turning from Christianity to Satanism to Atheism, since he has continuously done interviews about it. Allmusic describes Vengeance Rising's history as "one of the most entertaining and bizarre stories in the realm of heavy metal"
