home in Toronto, Canada, and the other half at Lanois' other home in Silver Lake, California. Sessions also took place at NRG, Avatar, Pilot, Mission Sound, Quad Studios, The Loft and La Bella Vista. Mark Kiczula acted as the main engineer with assistance from Jim Keller, Chad Lupo, Guiliano Baglioni, Roberto Fulps and Matt Shane. Additional engineering was done by Fox Phelps, Adam Samuels and Daniel Mendez. Carrabba experimented with a variety of instruments from mandolins to metal flowers pots that substituted as drums. At the end of the month, Carrabba went on a solo tour of colleges and debuted some of the new songs. In September, the group supported U2 on their North American tour. In between these support dates, the group performed a few club shows. Prior to starting the tour, Carrabba said the album required mixing. Despite this, material was still being recorded up to January 2006. Lanois left the project; Carrabba wanted to record another track, at which point Gilmore was brought in. Carrabba subsequently went on a song writing binge, creating six songs across four days. Sometime afterwards, Carrabba decided to rework the Lanois-produced material with Gilmore, while retaining some of Lanois' contributions. In March, Gilmore and Carrabba recorded an album's worth of songs. Gilmore is credited as producing the majority of the album, with the exception of "Heaven Here" which is credited to him and Lanois. Lanois also received a producer credit for the vocals on "Reason to Believe". Marsh said that due to the structure of the songs and melodies, the recording process give him a "great opportunity to create space." Andy Wallace mixed all of the album, except for "Don't Wait" (mixed by Gilmore), at Soundtrack Studios in New York City. He was aided by Pro Tools engineer John O'Mahony and assisted by Mike Scielzi, Paul Suarez ad Jan Petrov. Ted Jensen mastered the recordings at Sterling Sound. Adam Duritz of Counting Crows provided additional vocals on "So Long, So Long", while Susan Sherouse contributed violin and vocals.
