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. Read more about Borbetomagus on Last.fm.
