If you could travel back in time and see any band/artist in their prime, who would it be and why? Why do you think Neil Diamond, Elton John, and the others lasted as long as they did? If you could pick any music act to see in concert today, who would it be and why? Which of today’s stars do you think we’ll still be hearing from and seeing (quality) 10 years from now? Why? Who might just be disposable pop (low brow/trash) that we won’t even remember in 2030? Why?
The answer should include references to the articles above and should be max of 300 word
