Chelsea Grin is an American deathcore band. They were founded in Salt Lake City, Utah in 2007 by Alex Koehler and (former) guitarist Chris Kilbourn. Originally named “Ahaziah”, the band continued to recruit members and gained bassist Austin Marticorena. Marticorena introduced Andrew Carlston to Chelsea Grin and assisted in rewriting their current songs as well as the creation of new material. This writing process lead to the tracks listed on their first release, a self-titled EP that was first streamed and released online and then released in Compact Disc format worldwide on July 27, 2008.
