In late February and early March 2007, the band headlined a North American with support from Underoath and Armor for Sleep. On April 2, "My Blue Heaven" was released as a single and released to radio a week later. From late July to early September, the band participated in the 2007 Projekt Revolution tour with Linkin Park. On August 3 it was announced that O'Connell had injured his back, and he was replaced by Matchbook Romance drummer Aaron Stern for the remainder of the tour. Shortly after the tour Mascherino left the band, although his departure was not announced until early October. He said, "It was getting to the point where I felt I had taken the road as long as I possibly could," and his compositions were "more pop than anyone else the band wanted to go." Mascherino had written over 45 songs, most intended for "Louder Now" but turned down by the band. He began a solo project, the Color Fred.
