Lifesavers Underground (aka LSU, and L.S. Underground) was a musical project created by Michael Knott.

In 1987, Lifesavers Underground released their debut album, Shaded Pain. This was followed in 1989 with Wakin' Up the Dead.

This Is the Healing, was released in 1991; the album utilised a drum machine, while Knott played most of the musical instruments. The Grape Prophet (1993) was the first of rock operas by Knott.

Released in 1993, the fifth album was Cash in Chaos: World Tour. At this point Knott announced that he was changing the name of LSU to 'Cash in Chaos' (hence the mixed band name for this release).

Grace Shaker was released in 1994, which was followed in 1998 by Dogfish Jones, another rock opera.
