As for me, I'll shortlist this . Back in CO, I had been to Buck cherry, All That Remains, Five finger Death punch and Orgy, Oliver Heldens There were more dj/ edm/ trance showss but I can't recall at this time all of them
In MI, I got to see James Hype, Ian Bluestone, and Probably the most memorable was Darude. I actually got to shake hands with him which for me was an incredible experience, as his music was influential in my becoming a DJ
