Ozzy Osbourne is the unlikely choice to croon Bob Dylan's MASTERS OF WAR on a new metal reworking of the folk rocker's classics. Mountain stars Leslie West and Corky Laing have rearranged and recorded a collection of Dylan tunes and they asked Ozzy to join them in the studio. The covers album also features Allman Brothers Band guitarist Warren Haynes. Osbourne is a longtime Mountain fan - he covered the group's Mississippi Queen on his Prince of Darkness box set in 2005.
