Formed in 1991 by Tom Connelly, Mike Score, Chris Bozeth (orginal Merauder guitarist) and Sam Carbone (RIP). All Out War combined thrash metal and hardcore at a time when very few bands were doing so. After a short time, bass player Erik Carrillo, guitarist Chris Chisholm, and Jim Antonelli joined the band and (along with Connelly and Score) became the core members who wrote most of All Out War's first two records and even contributed to all other recordings. All Out War has continued to write, record and perform live once in a while throughout the years.
