AC/DC have endured a rough year, but are soldiering on with a new album, 'Rock or Bust,' due out Dec. 2. The band had to make the difficult decision to continue on without guitarist Malcolm Young, who is suffering from dementia.

We sat down with guitarist Angus Young and singer Brian Johnson to discuss Malcolm's absence from the band and the decision to keep going without him. They also talked about the contributions of Stevie Young, nephew of Angus and Malcolm, who has stepped in to fill Malcolm's shoes in the band.

Check out our exclusive video interview with Angus Young and Brian Johnson above. And pick up AC/DC's new album, 'Rock or Bust,' at iTunes.
