Hoglan also was recruited by Vancouver thrash metal band The Almighty Punchdrunk, and appeared as a band member for their only album to date, Music for Them Asses, released in 2001. Hoglan is working with Dethklok, the band from the animated TV show Metalocalypse. The show was co-created by stand-up comedian/actor/musician Brendon Small, who also composes or performs all of the music. Hoglan features in Dethklok's debut album, The Dethalbum, which was released on September 25, 2007. He toured with Brendon Small and the live band during the summer of 2008. Besides working with Dethklok, Hoglan is also a guest star by voicing a health inspector in one episode of the series. He later performed on Dethalbum II, the sequel album released on September 29, 2009, and again toured with Dethklok. The two later collaborated to make Brendon Small's Galaktikon using extra studio time from the Dethklok studio sessions. Hoglan filled in as the drummer for Unearth when their then drummer, Mike Justian, quit while on tour. He has also joined the metal band Pitch Black Forecast, with Mushroomhead singer Jason Popson, as the band's permanent drummer. Even more recently, Hoglan was announced as the drummer for the reunited Bay Area Thrash metal band Forbidden's reunion tour, replacing original drummer Paul Bostaph. Hoglan played drums on Zimmers Hole's third studio album When You Were Shouting at the Devil...We Were in League With Satan in 2008. In June 2011, he reunited with Testament, to record their eleventh studio album Dark Roots of Earth. On that album, he filled in for Paul Bostaph, who was unable to participate in the recording sessions because of a "serious injury". In 2012, he began touring with Testament, and on January 27 filled in for Charlie Benante of Anthrax. Although Hoglan was initially brought back to the band as a temporary drummer (in a fashion similar to his initial tenure when he recorded the Demonic album), he had since rejoined as a permanent member of Testament, recording two more albums with the band – Brotherhood of the Snake (2016) and Titans of Creation (2020) – and surpassing original drummer Louie Clemente as their longest-serving drummer. In 2018, Hoglan played with both Anthrax and Testament on the same nights during the Slayer farewell tour while Charlie Benante was recovering from carpal tunnel syndrome. Hoglan announced his second departure from Testament on January 21, 2022. Gene was the
