Tourniquet is an american christian thrash metal band, based out of California. Formed in 1989, the band takes its name from the medical device called a tourniquet - a last resort to stop serious bleeding. The current members of Tourniquet are Ted Kirkpatrick (drums), Luke Easter (vocals), Steve Andino (bass) and Aaron Guerra (guitar, vocals).

The band's sound took a sharp turn from their early thrash metal days, following the departure of original vocalist Guy Ritter. In the interim, the band recorded a "live in studio" album with Les Carlsen of Bloodgood. The following album, Vanishing Lessons was much more hard rock, but no less technical. After another EP, Gary Lennaire left the band.

The band's latest release, Where Moth and Rust Destroy, features special guests Marty Friedman, formerly of Megadeth, and Bruce Franklin, formerly of Trouble, on lead guitar (tourniquet had previously covered Trouble's The Tempter on their live EP).
