After forming BLACK SABBATH in 1969, Ozzy Osbourne, Tony Iommi, Terry “Geezer” Butler, and Bill Ward went on to record one of the most influential canons of music in the history of rock and roll.

Warner Bros./Rhino brings together the original quartet’s groundbreaking eight-album run for Black Sabbath: The Complete Studio Albums (1970-1978). The hard-hitting, eight-disc boxed set will be available on April 15.

Presented in a clamshell box, the set contains all of the studio albums Black Sabbath recorded for Warner Bros. Records during the 1970’s, including its iconic, eponymous debut (1970), the multi-platinum landmark Paranoid (1970), the platinum albums Master Of Reality (1971), Vol. 4 (1972), and Sabbath Bloody Sabbath (1973), as well as the gold albums Sabotage (1975), Technical Ecstasy (1976), and Never Say Die! (1978).

The past few months have been busy ones for Black Sabbath. Following hugely successful shows in North and South America, Australia, Asia and Europe, the band won its second Grammy Award when the song 'God Is Dead?' picked up the trophy for Best Metal Performance.

The group will kick off another North American tour on March 31 with a show at Barclays Center in Brooklyn, NY. In the weeks that follow, the trek will hit ten cities in Canada, including stops in Quebec, Montreal, Ottawa, Calgary and Edmonton, before it wraps on April 26 at the Hollywood Bowl in Los Angeles, CA. These dates are part of the band’s final shows of its 2013-14 world tour in support of its first studio album in 35 years, 13. A resounding success, the album entered the charts at #1 in 13 countries (including their first #1 in the US). Another run of European festivals and headlining shows will follow this summer.
