In 1997, after Hater broke up, McBain participated in the first Desert Sessions, a musical project led by Queens of the Stone Age frontman Josh Homme.
He was a live member of the Queens of the Stone Age for their first three shows, and co-wrote the song "Regular John" which appears on their self-titled debut album.
Notable appearances include keyboardist Glenn Slater of folk rock group The Walkabouts, Eddie Vedder of Pearl Jam and Josh Homme of Queens of the Stone Age and Kyuss.
In 2004, McBain moved to San Francisco, refining material that he had accumulated which he believed was not in step with the Wellwater Conspiracy's garage rock style.
In 2012 McBain collaborated with Carlton Melton on their Smoke Drip 12 inch LP [4] Monster Magnet Hater Devilhead Wellwater Conspiracy Solo work Other contributions
