Good news: AC/DC will release their 15th studio album, "Rock Or Bust," on Nov. 28. The bad news? Malcolm Young has officially retired.

The new album, which was recorded in 10 days, will be the first in the band's 40-year career without Malcom, But the band has tapped Angus and Malcolm’s nephew, Steve, as guitarist on the new album and upcoming tour.

“Unfortunately, due to the nature of Malcolm’s illness, he will not be rejoining the band,” AC/DC announced in a statement issued by their label, Alberts and Sony Music Australia.
