The Academy of Contemporary Music at the University of Central Oklahoma recently hosted master classes for its students with Maynard James Keenan, lead vocalist for the bands Tool, Puscifer and A Perfect Circle, and Jim James, frontman for the band My Morning Jacket.

Keenan, often referred to by his initials MJK, is best known as the lead vocalist for Grammy Award-winning progressive metal band Tool, which emerged in the early ‘90s and bridged the gap between classic heavy metal and alternative rock music. Though MJK’s fame stems from his successful music career, he is also an actor, comedian, winemaker and philanthropist. His memoir, “A Perfect Union of Contrary Things,” is scheduled to release this fall.
