Tourniquet was an American Christian metal band that formed in Los Angeles in 1990. It was founded by Ted Kirkpatrick, Guy Ritter, and Gary Lenaire. Tourniquet primarily played a mixture of thrash and progressive metal and was influenced by additional, non-rock forms of music such as classical and world music. The band earned six GMA Dove Award nominations and won multiple recognitions from the readers of HM Magazine, including "Favorite Band of the 1990s" and "Favorite Album of the 1990s" for Pathogenic Ocular Dissonance. They released ten studio albums, two live albums, four compilation albums, one EP, and several video releases. The last Tourniquet lineup consisted of Ted Kirkpatrick and Aaron Guerra. The band disbanded after Kirkpatrick's death in 2022.
Tourniquet has sold more than 300,000 albums. In addition to their use of classical music, the band is known for frequently using medical terminology in their album and song titles and lyrics. The band's 2003 release, Where Moth and Rust Destroy, features special guests Marty Friedman and Bruce Franklin, both on lead guitar.
