Evergreen Terrace have sent out an update on their current status and plans for the year:

After 9 years and some change of Evergreen Terrace, Jason Southwell has decided to leave the band. Farewell to Jason! Craig, Kyle, and [Josh] have been busy writing new jams for a new record. As of right now it looks like we will be getting into the studio around May, to have a late summer/early fall release.

The band released Wolfbiker in 2007.
