Stewart also plays on the Godsmack single "I Stand Alone" which was first released on the Scorpion King soundtrack in 2002 and later appeared on the band's third studio album Faceless after his departure.

[8] After leaving Godsmack, Stewart briefly joined ex-Van Halen and Extreme vocalist Gary Cherone's band Tribe of Judah as touring drummer.

He also helped guitarist and chief songwriter Carl Bell and bassist Jeff Abercrombie audition singers after Brett Scallions' departure in 2006.

Stewart was unable to participate in the recording of the Fuel album Angels & Devils due to other commitments, but was invited to join the band after the cd was completed, but not yet released.

Since Fuel had not been touring for a while,[15] Stewart joined Portland rock band Everclear in August 2008, replacing Brett Snyder on drums.

[16] Stewart departed from Everclear in 2009 after the recording of their 2009 release In A Different Light when most of the band lineup was jettisoned by Art Alexakis.

[17] By mid-2009, he began working with Lo-Pro again to finish up, and tour in support of, their two releases, the Letting Go EP and The Beautiful Sounds of Revenge.
