Malcolm Young has left AC/DC; nephew will replace him in lineup

The rhythm guitar player and founding member of heavy metal legends AC/DC, Malcolm Young, will no longer be playing with the band due to an extended, serious illness.

"Unfortunately, due to the nature of Malcolm's condition, he will not be returning to the band," the band said in a statement on its website. "AC/DC will undertake a world tour in support of 'Rock or Bust' in 2015. Stevie Young, nephew of founding members Angus and Malcolm Young, plays rhythm guitar on 'Rock or Bust' and will accompany the band on tour."

Turner Sports will give a sneak peek of one track, ‘Play Ball,’ during its 2014 Major League Baseball Postseason coverage, starting September 27.

AC/DC is stingy with new releases. "Rock or Bust" is only the band's third album since 1990. The band was started by brothers Malcolm and Angus Young in 1973.
