AC/DC ( B18 )

On 4 November, AC/DC were announced as the Business Review Weekly top Australian earner (entertainment) for 2009 with earnings of $105 million. This displaced The Wiggles from the number one spot for the first time in four years.

On 19 April 2010, AC/DC released Iron Man 2, the soundtrack for the eponymous film which compiled earlier tracks from the band's studio albums. One month later, the band headlined Download Festival at Donington Park, and closed the Black Ice World Tour in Bilbao, Spain on 28 June 2010, after 20 months in which AC/DC went to 108 cities in over 28 countries, with an estimated audience of over five million people. Three concerts in December 2009 at the River Plate Stadium in Argentina were released as the DVD Live at River Plate on 10 May 2011. An exclusive single from the DVD, featuring the songs "Shoot to Thrill" and "War Machine", was issued on Record Store Day. In 2011, the band also issued on DVD and Blu-ray the concert movie AC/DC: Let There Be Rock, which had its theatrical release in 1980.

Multiple lineup changes, Rock or Bust (2011–2017)

Angus stated in an interview in early May 2011 that the band was beginning to plan another world tour, saying, "Now we're thinking, 'How can we ever better the 'Black Ice' world tour?' But we will." At the band's Live at River Plate DVD premiere on 6 May 2011 at the Hammersmith Apollo in London, England, Angus said that there were plans for the group to release a new studio album "within the next couple of years", which the tour would support.

In May 2012, Malcolm Young confirmed that the band were working on a potential follow-up to 2008's Black Ice. But he warned that fans were in for a longer wait than expected, after lead singer Brian Johnson suggested there would be new material the next year. Malcolm stated, "You know what Brian's like. He just says things and then walks away. It'll be a little while – a year or two anyway. I've been doing some jamming on some song ideas but I do that all the time, as do the rest of the band.
