The headbanging faithful drooled over a 2011 announcement that the original Black Sabbath lineup—the first and greatest heavy-metal band—was reuniting. That all fell apart last year, when drummer Bill Ward broke ranks over a contract dispute, but the train rolled on without him. Ozzy Osbourne, Tony Iommi and Geezer Butler kept at it and, against all odds, issued a highly impressive Rick Rubin–helmed comeback, 13, last year. Here, the trio, plus fill-in drummer Tommy Clufetos, hits NYC for the first time since the album's release. Prepare to tremble before immortal classics such as "Black Sabbath" and "Iron Man," and hear a few of the new joints as well.
