From Under the Cork Tree is the second studio album by the American rock band Fall Out Boy, released on May 3, 2005, through Island Records as the band's major label debut. The music was composed by lead vocalist and guitarist Patrick Stump, with all lyrics penned by bassist Pete Wentz, continuing the band's songwriting approach they took for some songs on their prior 2003 effort Take This to Your Grave. Neal Avron handled production duties. Commenting on the record's lyrical themes, Wentz said the lyrics were about "the anxiety and depression that goes along with looking at your own life." In support of their release the group headlined tours worldwide and played at various music festivals. For their Black Clouds and Underdogs tour the album was re-released as From Under the Cork Tree (Limited "Black Clouds and Underdogs" Edition), featuring new songs and remixes.
