Steve Larson (AKA "L.L. Cool Steve" or "Dirty") is the former lead guitarist for Roger Clyne and the Peacemakers. Prior to Roger Clyne and the Peacemakers, his previous bands include Dialectrics and Dead Hot Workshop, which he formed in 1989 with Brent Babb. In addition to his work with the Peacemakers, Larson also has his own side project, The Steve Larson Band.

Larson has opened for many artists solo and with his Steve Larson Band, including Shooter Jennings and Hank III.

Larson was let go from RCPM in January of 2009 for reasons the band would not specify (the band cited personal reasons through an on-line press release.) He is currently hosting open mic nights and playing solo in the east valley of Phoenix, AZ. He has recently began a new project with James Parks called The Larson Parks Band.
