I don't think I've posted on here, but let's see:

~Britney Spears (my first concert WAY back in 2000/2001 and a second time in 2009)

~Carrie Underwood (2008 and 2010)

~Trans-Siberian Orchestra (2008, I think)

~Aerosmith (2015)

~Andre Rieu (2010)

~Alice Cooper's "Christmas Pudding" *if it counts, cause several artists performed including Johnny freaking Depp with the Hollywood Vampires* (2016)

~Taylor Swift (2015)

~Bernadette Peters (2004, 2006, and 2016)
