Task: Question Answering
Input (English): Passage: List of AC/DC members -- Shortly after the release of the group's fourth studio album Let There Be Rock in 1977, Evans was fired from AC/DC due to growing tensions with the Young brothers. He was replaced by English bassist Cliff Williams. After two more studio albums, Scott died on 19 February 1980 of acute alcohol poisoning. The band briefly considered breaking up, but later enlisted former Geordie frontman Brian Johnson as Scott's replacement. In 1983, following a physical altercation with Malcolm Young and ongoing problems with substance abuse, Rudd was fired from AC/DC. He was replaced by Simon Wright, who remained until 1989 before joining Dio. Wright was replaced by Welsh drummer Chris Slade for five years, before Rudd returned in late 1994 during sessions for the group's thirteenth studio album Ballbreaker.
