Both of the albums, and especially the second one, have received critical acclaim worldwide. After the release of The Sideshow, Griffin's singer at the time, Tommy Sebastian, left the band, and was replaced by Peter Beck. In 2003, they inked a deal with the Norwegian label FaceFront, who released Griffin's third album entitled No Holds Barred in September the same year. This album was co-produced by Alexi Laiho from Children of Bodom and Sinergy. He also contributed with some guitar and back-up vocals. A Japanese label, Spiritual Beast, bought the distribution rights for the Asian market for that particular recording. The album got standing ovations from the press, they claimed that Griffin was on the very edge of conquering the Norwegian metal throne. They recorded a professional video for the first time with the song The Sentence. This video has since then had massive airplay on Norwegian television, and was among the top 5 requested tracks on a national metal video show for more than six months! For the fourth album, Griffin signed a worldwide deal with Spiritual Beast (excluding Norway which is still FaceFront's area). This album, entitled Lifeforce, was produced by legendary King Diamond guitarplayer, Andy LaRocque. Lifeforce has a European distribution through Massacre Records. After the release of Lifeforce, both Pete and Marcus parted ways with Griffin. Marcus Silver soon formed a new band, Triosphere.
Marcus was replaced by an 18 year old guitar virtuoso named Roar “Emperoar” Naustvoll who has been a long time fan of the band. Pete was replaced by Rolf Bakken, one of the most acclaimed rock singers in the local scene. The band is once again ready to hit the road and tour again. In May 2006 Griffin will support King Diamond on a European tour.
Currently Griffin is recording their 5th album, The Ultimate Demise. Peter Beck make a visit as the Griffin was making their recordings. The new album include support vocals from Pete.
Roar, Kai, and Johnny are endorsed by ESP Guitars and receive product support. They are also endorsed by ENGL Amplifiers.
