"The worst act I've seen live is Buckcherry. Their radio length songs were what I enjoyed, but their live version of songs just ran on to the point of "this song should have ended 5 minutes ago.". 

Every other artist that I've seen live has been good to great."

"Metallica/Guns N' Roses (plus Faith No More) in Montreal's Olympic Stadium in August 1992, the concert where James Hetfield got burned by pyrotechnics and then Axl Rose had laryngitis and quit after just six songs, leading to a small riot.

I was only 17 and had a long commute home so I left before things got too rowdy."

"Meatloaf in Vegas in 2014. I s**t you not that the interlude portion of “Paradise by the Dashboard Light” was about 15 minutes of nonsense—complete aural jibberish. My mom, who had been a pretty big Meatloaf fan to that point, at one point leaned over to ask if I thought we were being pranked. ."
