I saw a lot of concerts partly because I used to work in a popular record store in the late 80's/early 90's ("Record store" sounds so archaic hahaha). I had a good relationship with the various company reps & often got tickets and sometimes backstage passes.
I also worked security during the late 90's at a couple of 2000-3000 seaters.
My first ever rock concert was KISS at the Montreal Forum in 1977 during the "Love Gun" tour. I went with my older cousin and my jean jacket reeked of weed when I got home.
It just blew my 9 year old mind. Total attack of all the senses.
The most memorable off the top of my head:
-Queen in 1980
-Genesis
-Miles Davis at the Montreal Spectrum, 1985. Just. Wow.
-Rush (3 times). I usually went to pee during drum solos but never at a Rush concert. RIP Neil Peart.
-AC/DC 3 times. Always an action packed 2 hour+ show.
-Iron Maiden 2 times. "Piece of mind" & "Powerslave" tour.
-Metallica's "And Justice for All" tour. Went backstage. James Hetfield was super nice, Jason Newstead was on happy PR mode. Kirk Hammett walked by giving us all the finger. Hetfield said he "had a bad night"
-Whitesnake & Motley Crue double bill
-Alice in Chains opening for Iggy Pop at the Montreal Spectrum
-The Replacements
-Stevie Ray Vaughn
-Marillion
-Ratt opening for Ozzy at the Forum
-Van Halen's 1984 tour. Went to pee during David Lee Roth's "Solo". He did some sort of martial art choreography...
-U2's "Unforgettable Fire" tour.
-Ice-T with Bodycount at the Montreal Spectrum during New Year's Eve.
-White Zombie & Pantera double bill.
-Rollins Band at Foufounes Électriques
-INXS at the Metropolis in 1997.
That was a fun night. I was working security and sitting in "the pit" between the crowd & the stage. We had specific instructions to just sit there because the band had their own security dudes. Michael Hutchence was on fire, running around and even climbing to the upper balconies. Nicolas Cage was sitting in a VIP balcony and waving at the crowd (He was in town filming "Snake Eyes).
Hutchence would die a couple months later.
