for the Foo Fighters' "Low", a cameo in the music video for the song "Sexx Laws" by Beck, and the video for "Humility" by Gorillaz. In addition to appearing in videos, Black and Gass sang backup vocals on the 2003 Styx album Cyclorama, on the song "Kiss Your Ass Goodbye". Tenacious D lent backing vocals to The Vandals album Look What I Almost Stepped In..., on the song "Fourteen". Tenacious D appeared on KROQ-FM's twelfth full-length Christmas compilation, Swallow My Eggnog, with Sum 41, on a song entitled "Things I Want". Gass appeared in the Good Charlotte music video for the song "Lifestyles of the Rich and Famous". Trainwreck Following Black's popularity in the film industry, he was unable to tour regularly with Gass, so Gass started Trainwreck, under the pseudonym "Klip Calhoun". The band also features JR Reed (Lee of Tenacious D) under the pseudonym "Darryl Donald", as well as Konesky and Spiker, who play lead guitar and bass. They have released a live album, Trainwreck Live, and a studio album The Wreckoning. Black occasionally appeared with the band under the name "Tuffy McFuckelby". Trainwreck broke up in 2010, but reunited in 2018 and announced that they were working on a new album. Kyle Gass Band Following the breakup of Trainwreck, Gass started Kyle Gass Band in 2011. The band released their first album, Kyle Gass Band in 2013 and Thundering Herd in 2016. The band features Mike Bray as lead singer, who used to open for Trainwreck shows as the lead singer for Band of Bigfoot. The band also features Konesky reprising his role as electric guitarist. Guitarings Gass and Konesky produced a YouTube series between 2009 and 2012, after Gass was annoyed at people uploading inaccurate guitar chord tutorials for Tenacious D songs. As well as uploading their own Tenacious D song tutorials, the duo also did numerous videos featuring equipment reviews, music shop tours and answering fan mail. From 2013 to 2015, Konesky hosted the series by himself, this stint including the "Weekly Lick" series. Gass would return in 2015 to perform "Manchild" and "Bro Ho" from the Kyle Gass Band's album, as well as giving tutorials on the songs. The Kyle Gass Band does not have their own YouTube channel, so uses the Guitarings channel to upload many of their videos.
