Containing much rare and previously unpublished material culled from Popoff’s interviews over the last decade with all the principal members of the band, Black Sabbath: Doom Let Loose is an exhaustive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. The drugs, drink, depression, and doom surrounding this band from the start have imbued songs like “The Wizard,” “Paranoid,” “Iron Man” “War Pigs,” “Children of the Grave” and “Heaven and Hell” with an almost supernatural importance among lovers of dark music. In the wider realm, full albums such as Master of Reality, Sabbath Bloody Sabbath, Sabotage, and Heaven and Hell show up with regularity on lists of greatest records of all time. Doom Let Loose explains how such classics came to be. It also deals with their tour history, documenting the places rocked, the bands who supported the Sabs, and most notably the trials and tribulations of the band and they tried to hold it together in the Satan-obsessed, drug-addled America of the Nixon era. Look for all manner of Sabbath photos and artefacts that make this examination of heavy metal’s fearsome foursome as feast for the eyes as well as the enquiring mind.
