Containing much rare and previously unpublished material culled from Popoff’s interviews over the last decade with all the principal members of the band, Black Sabbath: Doom Let Loose is an exhaustive song-by-song, album-by-album trek through the Sabs’ 37-year history. Numerous one-on-one conversations with Ozzy, Tony, Geezer, and Bill, as well as ten interviews with Ronnie James Dio, and additional interviews with supporting musicians such as Tony Martin, Ian Gillan, Glenn Hughes, Vinny Appice, and Neil Murray, make this full-colour retrospective a must for any fan.
