Metal Allegiance, the metal supergroup featuring core members David Ellefson (Megadeth), Alex Skolnick (Testament), Mike Portnoy (ex-Dream Theater, etc.), and Mark Menghi, along with multiple special guests, have announced a special Brooklyn, NY show in which they will be covering Black Sabbath‘s 1970 self-titled album in its entirety. The event will take place at the Brooklyn Bowl on October 27 and Judas Priestess, Alehkaine’s Gun, and Magus Beast will serve as support. It’s worth noting that Ellefson will miss the show due to his commitments to Megadeth. So far, Overkill’s Bobby Blitz has been the only guest to be announced.
