Atreyu is an American metalcore band from Orange County, California, formed in 1998. The band consists of vocalist/lyricist Alex Varkatzas, guitarists Dan Jacobs and Travis Miguel, bassist Marc McKnight and drummer/vocalist Brandon Saller. Originally named Retribution, they changed their name to "Atreyu" (after the character of the same name from the fantasy book/movie The Neverending Story), when they found out that another band from Hemet, California had already been using Retribution. They have released five studio albums: Suicide Notes and Butterfly Kisses, The Curse, A Death-Grip on Yesterday, Lead Sails Paper Anchor, and Congregation of the Damned.

In 1998, Atreyu released an independent seven-track EP titled Visions. The album was sold at their live performances. Their second release, was a short five-track EP titled Fractures in the Facade of Your Porcelain Beauty released by underground label Tribunal Records and featured tracks that would be re-worked for later releases. Atreyu signed with Victory Records in 2001, and their most critically acclaimed works would be to come from these releases.
