Guitarist Warren DeMartini and vocalist Stephen Pearcy of Ratt  joined the Chelsea Girls on stage at The Roxy in West Hollywood last Friday. The band recently signed with Loud & Proud/Roadrunner Records and soon will begin recording their first new material since the 1999 self-titled album. The album is expected out in the fall and will lead to a massive world tour. See the band performing "Wanted Man" at House of Blues in New orleans last August below.
