Bongripper is a four-piece instrumental sludge metal band from Chicago, IL, United States. Since 2005, they have self-released seven recordings. Known for a deafening and intense live performance, the band thrives on an unrelenting sound that can compete with any of the heaviest metal bands of their genre, covering a vast range of genres, from noise, drone doom, and dark ambient to post-metal, their music stands out as a great example of experimental metal.

The band formed in 2005, when a simple jam session began the making of their first album, “The Great Barrier Reefer.” Clocking in at 79 minutes and 23 seconds, The Great Barrier Reefer is a one track doom experimentation. The band released a very small amount of copies, and have yet to re-release the album since then.

In 2007, Bongripper released their second full-length album entitled, “Hippie KIller.” The 10-track album has found its way into many stoner fans’ libraries. Tracks such as Reefer Sutherland helped Hippie Killer receive a nomination for the stoner-sludge album of the year by Metalstorm.net.

Later in 2007, Bongripper released an experimental drone album entitled “Heroin.” The album was packaged as a heroin kit, complete with a lighter, rubberband, and spoon. There were a very small number of these made, and they are nearly impossible to find today.
