I am just really happy people who have not had the chance to see them will be able to get one more shot. That is always a big upside when these legacy acts go out on a new tour.
Personally, I am pretty content with my AC/DC run- 2009 Black Ice (on the floor and it was awesome!), Rock or Bust 2015 in the rafters, and Axl/DC in 2016 from the lower bowl. Even got to meet the entire band sans Cliff in 2016! Pretty damn good trifecta of shows if you ask me, especially that 2009 show. That was mind-blowing with the Back in Black lineup and the train on- stage. A quintessential AC/DC show, it felt like Donnington had come to life before my very eyes.
That being said, if they came to Detroit I would strongly consider one last hurrah.
