Bongripper are an experimental sludge/doom metal band from Chicago, Illinois.  The band formed in 2005 after a simple jam session turned into something much more serious.  Their first album, The Great Barrier Reefer, consists of only one track that is nearly 80 minutes long; the album was a very limited release, though it was finally rereleased in October 2012 due to popular demand.   Their sound is very experimental, tapping into elements of a vast range of genres, including noise, drone doom, and ambient music.  Bongripper's most recent full-length album was released in 2010 and received much acclaim, and their live performances are known for their crushing sound and intensity.  

They will be making their second Maryland Deathfest appearance in 2016.
