Search for a new drummer On September 8, 2010, drummer
Mike Portnoy announced that he would be leaving Dream Theater, citing better relationships in other projects, burnout, and his desire for a break as reasons. Elaborating on the situation for
MusicRadar, guitarist
John Petrucci revealed that, originally, Portnoy did not want to leave the band, and that he only wanted to take a five-year break. Only after the rest of the band rejected his proposal did Portnoy decide to officially quit. Petrucci has called Portnoy's departure one of the hardest things Dream Theater have had to face, and speaking of when he first heard the news, keyboardist
Jordan Rudess recounted, "You know, just to give you an idea of how deep this was to lose him, how difficult it was... after we got off the phone with him... I literally sat on the steps of my studio and cried. This is a guy who's a friend of mine, who we all love and admire. We didn't want to see it come crashing down." In April 2011, the band announced that Mangini was the drummer selected via a three-part
YouTube documentary series called
The Spirit Carries On. Shortly after Mangini joined Dream Theater, Portnoy e-mailed the band asking to rejoin, but his attempt was rebuffed. Reflecting on his arrival to the band, Mangini told
Noisecreep, "As I see it, as I look back, I really think what happened was that this band kind of started over. They were in a new place as they looked for a drummer, and when I got the news, after the shock wore off, I knew what I wanted to do – which was just basically come in and try to support where they wanted to go. They had a vision, they had great ideas, and I just wanted to help them achieve those things."
Writing and recording On January 3, 2011, Dream Theater entered Cove City Sound Studios to begin working on a new album. Although John Petrucci brought in demos, riffs, and songs from home, the album was mostly written in the studio. Writing was completed on March 2 and done without Mike Mangini. The band made demos for all the songs with drums already programmed, then sent them to Mangini who learned the parts and "added his own stuff." Reflecting on the writing process for
Rock Your Life, Jordan Rudess explained that the band's approach was more open to his keyboards than in the past, and that after Mike Portnoy's departure, he and Petrucci "became, like, free." Vocalist
James LaBrie and bassist
John Myung each contributed more to the writing than they had in recent years. On April 14, LaBrie began tracking vocals, and by June 28, the album's mixing and mastering, which were handled by
Andy Wallace, All of LaBrie's vocals were recorded in Canada with engineer Richard Chycki; originally, LaBrie planned to only record the album's first two songs away from New York City, but after flying there to finish the remainder of the vocals, decided to go back to Canada because "it just didn't feel right." ==Composition==
