Nearly two decades after Ozzy’s departure, the original Black Sabbath reunite and deliver a live record stuffed with ’70s landmarks. The years have not dulled the doom pioneers’ heaviness: The whiplash time changes built into the devastating stoner-metal anthem “Sweet Leaf” are still dazzlingly agile, while Ozzy’s icy shriek proves ageless when leading fans through a mass chant on the funereal stomper “War Pigs”. The quartet also contribute two new studio recordings, including “Selling My Soul”, which rekindles old-school Sabbath’s downtuned blues and creeping paranoia.
