Uh... I've lost count, but it's been hundreds.
I saw Panic! At The Disco, Fall Out Boy, and My Chemical Romance before they were big names (P!ATD on their first tour ever) and I've been attending concerts since I was an infant. I've got so many crazy stories, some of which I've told before. Flirted with Skrillex when we were teenagers, partied with bands, all sorts of things.
K-pop wise, I've seen Monsta X four times, and my most recent concert was a trip to L.A. to see Seventeen.
Upcoming concerts are Monsta X, My Chemical Romance, and Simple Plan/New Found Glory.
