At 13, Saller was invited by his older brother Ryan to join a band started by some of his friends, Dan Jacobs and Alex Varkatzas. The three of them formed a street punk band called Retribution, which by 1998, had adapted a heavier sound and changed names to Atreyu after the main character of The Neverending Story. The band signed to Victory Records in 2001 and released 3 albums under the label, Suicide Notes and Butterfly Kisses in 2002, The Curse in 2004, and A Death-Grip on Yesterday in 2006. The band later joined major label Hollywood Records and released 2007's Lead Sails Paper Anchor and 2009's Congregation of the Damned. After over 10 years of worldwide success, the band embarked on hiatus, but returned in 2014. They released their sixth studio album, Long Live in 2015.
