Three Days Grace was released on July 22, 2003, by which time "(I Hate) Everything About You" was already a hit on alternative radio stations in Canada. The band toured extensively behind the record for the next two years as both a supporting act and headliners, but after a while, life on the road left the band, especially Gontier, feeling isolated and alone. Consequently, this theme of disconnection -- coupled with the realization that one was, in fact, not alone -- would serve as the basis for their follow-up album. Getting back to their roots by writing the record in the Ontario countryside, One-X was released in June 2006. The album, which hit number five on the Billboard Top 200, marked the recorded debut of the band's second guitarist, Barry Stock. Three Days Grace supported One-X throughout the summer on dates alongside , , and , while "Animal I Have Become" became a number one modern rock hit.
When Three Days Grace released Transit Of Venus in October of 2012, the album immediately started gaining traction with radio-friendly songs like “Chalk Outline” and “The High Road.” The future was looking bright for the Canadian hard rock quartet as they prepared to embark upon a co-headlining tour with fellow hard rockers – Shinedown – when frontman, Adam Gontier, shocked everyone by announcing his departure from the band.
