Bl'ast! released their first album, The Power Of Expression, in 1986. They recorded the album three times before releasing it. They first were signed by Green World Records. Bl'ast! caught the attention of SST Records, who signed them or their next release, 1987's It's In My Blood. That same year, a 7-inch was released, including a cover of Alice Cooper's "School's Out". They also were releasing new music on Santa Cruz Skateboard videos. SST and Santa Cruz Skateboards began shared videos and merchandise bridged by Bl'ast! as Neider had worked for the skateboard company for many years. The band's third release for SST was Take The Manic Ride, released in 1989.

In the 90s Bl'ast! took a break. Neider and Torgerson began Blackout, releasing one 7-inch under that name, and then LAB, who put out a 7-inch EP and a four-song CD and continued into the late 1990s, playing many shows with Fu Manchu. Former Kyuss and Fu Manchu drummer Brant Bjork moved to Santa Cruz to briefly join LAB before joining up with Fu Manchu. In 2001, Bl'ast! reunited for shows on the West Coast of the United States.

On September 3, 2013 Southern Lord and Dave Grohl released a remixed and remastered version of It's In My Blood, entitled Blood!. Following that release, original vocalist Clifford Dinsmore and guitarist Mike Neider recruited bassist Chuck Dukowski and drummer Dave Grohl to a new Bl'ast! EP, For Those Who've Graced The Fire to be released on Rise Records.

Mike Neider and Clifford Dinsmore have recruited bassist Nick Oliveri and drummer Joey Castillo to a new Bl'ast! lineup, with plans to tour and record new material.
