Despite all the bad blood and legal drama between the trio of late, Queens of the Stone Age frontman Josh Homme has joined Kyuss singer and former bandmate John Garcia on a track from ex-Queens and Kyuss bassist Nick Oliveri's new Mondo Generator album.

The complexities of the relationships between the three former Kyuss mates may be a little confusing for those not familiar with their collective back stories. The tale began when guitarist Josh Homme, bassist Nick Oliveri and vocalist John Garcia helped pioneer the "stoner rock" genre with Kyuss in the mid-90's. After a short-lived run with moderate success, the band split and  Homme began fronting his own band called Queens of the Stone Age, which was joined by Oliveri shortly after. A few years down the line, Homme had a falling out with Oliveri and fired the unpredictable bassist.

Fast forward to 2010 when Garcia attempted to revive the core lineup of Kyuss, all members were willing to participate except Homme. The Kyuss-reunion went on without him and began touring under the name Kyuss Lives! When news broke that the Garcia-lead project planned to release an album under the name, Homme was quick to take legal action to prevent them from doing so. Shortly after the lawsuit came about, Oliveri dropped out of Kyuss Lives! and sided with Homme's side of the argument.

Now Homme and Garcia can be heard together on a new song from the recently released Mondo Generator -- Oliveri's pseudonym -- album, 'Hell Comes to Your Heart.' Although their cameos were most likely recorded separately and prior to the legal drama, both Oliveri's former vocalists chime in on the track titled 'The Last Train.' This marks the first time that Homme and Oliveri have recorded together since his ousting from Queens in 2004.

Even though he avoided the courtroom in the Kyuss Lives! situation, Oliveri will not be so lucky when he faces four felony charges stemming from a 2011 standoff with the L.A.P.D. If found guilty on all four, Oliveri could be sentenced to 15 years in federal prison.
