From the band’s Facebook page:
“We are taking this opportunity to sadly inform you the six of us have decided at the end of the current european tour, Aaron will no longer be playing in Underoath. This was not a decision made in haste but a thought out and prayed upon group agreement. It in no way effects any of the shows left on this tour. They will still be our best efforts and enjoyable experiences for all.
For the future, Aaron will be pursuing other musical and ministry endeavors. As for the rest of us we will continue to work hard on the new Underoath record. We appreciate the love and support from everyone in the past and hope that all of us will continue to receive your support on our future paths. We love you guys. Tim, Grant, Aaron, James, Chris, and Spencer”
