In a note on his Facebook page, Ward described the Day of Errors sound as, "We play loud, hard, with overtures of gut-kicking heavy, heavy parts." The group features Ward on drums and vocals, Joe Amodea on guitar and vocals and All Hail the Yeti's Nick Diltz on bass and lead vocals. The trio will also be joined by percussionist Walter Earl and Ward's son, Aron, on keyboards.
Ward did not detail any immediate plans for Day of Errors, though closed his note saying, "More information will follow."
Ward's new group arrives as his old one, Black Sabbath, prepares to embark on their last set of live dates. The drummer and band acrimoniously split in 2012 before Sabbath recorded their final album, 13, replacing Ward with Rage Against the Machine's Brad Wilk.
At the time, Ward released a statement asking for a "signable contract" from his bandmates, but negotiations fell apart. In 2015 — after the release of 13, but before the launch of Sabbath's The End Tour — Ward issued another statement demanding an apology from frontman Ozzy Osbourne for "untrue" statements made about him. Osbourne refuted the statement and claimed that Ward was physically unwell to commit to touring and Sabbath had to move forward without him because of Tony Iommi's lymphoma diagnosis in 2012.
Sabbath ultimately continued without Ward, though in January the drummer refuted a claim made by Geezer Butler that he'd been invited to play Sabbath's final gig. "I will say that I wouldn't want to play only one gig when I am completely capable of touring," Ward told Rolling Stone. "I would not validate their untrue statements about my health by playing only one gig. Also, I wouldn't want to show up for only some of our fans and not for all our fans when I could have played multiple shows."
