return, they listened to a few rough mixes, which Benji Madden said sounded like all of the albums Benson had produced in the past and that he preferred the demo versions. Around this time, the band left Epic Records. Recording Madden contacted producer Don Gilmore and told him of the situation. Gilmore, who was in Europe at the time, suggested Madden take a break, and when he got home to listen to the recordings. When Gilmore heard the demos, he stated they were the band's best material to that point. Gilmore proposed going to Vancouver, Canada, and starting the recording process anew. Madden told the group's manager to postpone all engagements and held an emergency band meeting. The other members agreed about starting over and the band moved to Vancouver with Gilmore in January 2010. In a post on their website, Madden stated the band "needed to be in the studio with someone who understood the heart of [the] band. And what that is, it's YOU GUYS". The group took a handful of songs with them to Vancouver and wrote new ones. Sessions took place at The Armoury and The Warehouse Studio in Vancouver, and later at Studio Can Am in Tarzana, California. Recording was handled by Mark Kiczula with assistance from Mike Cashin and Josh Bowman. Sessions concluded in April. Gilmore mixed all of the tracks except "Last Night" and "Harlow's Song (Can't Dream Without You)", which were done by Serban Ghenea at MixStar Studios in Virginia Beach, Virginia. John Hanes served as mixing engineer and was assisted by Tim Roberts. Ghenea also did additional mixing on "Like It's Her Birthday". Bart Hendrickson and BC Smith played keyboards and did programming. Ted Jensen mastered the recordings at Sterling Sound Studios in New York City.
