Mother Superior was an American hard rock band based in Los Angeles and active from 1993 to 2011.

A power trio, they originally consisted of guitarist/vocalist Jim Wilson, bassist Marcus Blake and drummer Jason Mackenroth.

[3][4] In addition to playing live with the Rollins Band and U2 producer Daniel Lanois, Mother Superior (as a group or its members individually) have done session work with Daniel Lanois, Tony Visconti, Alice Cooper, Meat Loaf, Emmylou Harris, Sparks, Anthrax, Wayne Kramer, Lemmy, George Clinton, Iggy Pop, Mike Patton, Dig, and Queens of the Stone Age.

[citation needed] A few years after Mother Superior disbanded, vocalist Pearl Aday reached out to Wilson as a gift for her husband, guitarist Scott Ian of Anthrax.

Aday, Ian and Wilson were joined by bassist Joey Vera (Fates Warning, Armored Saint) and drummer John Tempesta (The Cult, Exodus, Testament, and White Zombie).
