One of AC/DC’s longest-running members is bowing out: bassist Cliff Williams, who started playing with the Australian metal gods in 1978, has confirmed that he is leaving once the band completes its current tour.

Williams announced his departure in a video message:

Williams took over the bass for the band following Mark Evans’ departure, and played on classic albums like 1979’s Highway to Hell and 1980’s Back in Black. His last studio outing with AC/DC was 2014’s Rock or Bust.

Angus Young, the band’s guitarist, is the sole remaining member from their late-70s heyday. Axl Rose recently joined AC/DC on tour as their vocalist.
