Mountain was the legendary American rock band led by Leslie West. The band was formed in 1969 and played one of it's early dates at the equally legendary Woodstock Festival in August 1969. In September 1969 Corky Laing joined Mountain replacing original drummer Norman Smart. This compilation is an archive release featuring recordings from Leslie's pre-Mountain band The Vagrants and Corky's pre- Mountain band Energy. The material contained in this release is extremely rare with some of the recordings being previously unreleased. Of major interest to Mountain fans will be the inclusion of previously unavailable recordings of Mountain taken from the sessions for their debut album Climbing
