On September 20, 2016, AC/DC wrapped up the final show of their iconic ‘Rock or Bust’ tour at Philadelphia’s Wells Fargo Center. The band never appeared on the concert stage again… that is until they kicked off their ‘Power Up’ tour on May 17th in Gelsenkirchen, Germany. For fans who packed the Veltins-Arena, it was well worth the 2,796-day wait.
