Borbetomagus are a free improvisation group.
Borbetomagus formed in 1979 when saxophone players Jim Sauter and Don Dietrich collaborated with electric guitarist Don Miller; bass guitarist Adam Nodelman was briefly a member. Their music has been described as "a huge, overpowering, take-no-prisoners mass of sound." One extended technique they use is called "bells together" where Sauter and Dietrich physically place the openings of their saxophones against each other.

Gnaw is an experimental drone / noise band from New York City, New York, United States formed in 2006 by Alan Dubin. Gnaw is the sawblade-wrapped-in-razorwire brainchild of Alan Dubin (Khanate, OLD), Carter Thornton (Enos Slaughter), Jun Mizumachi (Ike Yard), and Jamie Sykes (Thorr’s Hammer, Burning Witch). Their 2009 debut for Conspiracy Records “This Face” was further infected and finally delivered by engineer Brian Beatrice before being wrought for stage deployment with additional drummer Eric Neuser.

There are at least three bands with this name:
1) An American synthpunk duo of the '70s.
2) A death metal band hailing from Turkey, who pioneered the Turkish death metal scene.
3) A grunge/hardcore band from Milevsko, Czech Republic. 1) Suicide is an American duo that was one component of the late 1970s punk scene on the Lower East Side of New York City, USA. They are also considered to be one of the precusors of the no wave movement that started in the mid-70s and went into the mid-80s.
