Deeper Purple is a Deep Purple tribute band. Bassist/singer John Osmon and singer Mark Huff previously played together in a local Van Halen tribute, OU812.

In late 2010, Quiet Riot recruited Huff to replace the late Kevin DuBrow, who died in 2007. A documentary about him joining the band was being filmed when Quiet Riot appeared at the Ramona Mainstage on Friday, January 28, 2011.
