Digitally remastered edition of this 1972 album from the veteran Heavy Metal maniacs. By the time Black Sabbath began work on what was to be their fourth album in `72,  they were very much in the ascendant. Musically, the band weren't prepared to superglue themselves back into a comfort zone and just do what was expected of them. They wanted to go beyond the darkness and gloom which seemed to surround so much of their music until that point. Here was an opportunity to open Sabbath out to unexplored worlds, to be the band who led, rather than one of the many who merely followed. And they succeeded, as there's an elegance about Volume 4 which underscores the way in which the band had matured and developed, both as songwriters and musicians. This remastered and sumptuous gatefold digipak edition of the album boasts comprehensive story of the album sleeve-notes by renowned Rock critic Malcolm Dome  and a plethora of rare and previously unseen photographs and items of memorabilia.  Sanctuary. 2009.
