I spent my formative years with the understanding that I would never get to see KISS live and then, out of nowhere, they announced they were getting back together for the reunion tour in 96. Praise be! Took my now-wife on our third date to see them at the Summit (Compaq Center by this point?). When Gene's platform went out over the crowd, dude stopped damn near right over us. It was epic. (Also, Pushmonkey was the opening act, which was a real bonus as I would have seen them solo too.)
In my music room I have a framed copy of the Gibson ad featuring Ace and his custom guitar.
In my comic collection I still have the Kiss issue "printed with real KISS blood!"
Once, in high school, I went to Millennium in north Houston and saw Ace and Peter doing a show. Peter was meh af, but Ace fucking brought it. I was probably the youngest dude there, There was a part of the show where Ace said something like, "Do any of you remember my solo album? I think I'll do a song off of it now. You know the one!" Half the crowd screamed New York Groove and half screamed Rip It out. As loud as I could I screamed the one I wanted to hear, Ozone. Ace looked at me for a quick second with a subtle look of surprise on his face. I like to think he was taken aback by such a young kid pulling out one of his deep cuts. Could have been that he was surprised he had a song named Ozone and wondered what it must have sounded like. Who knows.
Later in that show I made my way to the front of the crowd. Now, mind you, I made it to the front for Peter's show, too, and got to high five the man. Was a highlight of my young life. So I tried to do the same for Ace. I got to the front and everyone had their hand out to touch the dude. He looks me square in the fucking eyes and smirks. He didn't meet my high five, left me hanging, and smirked at me like an asshole. Don't care, still love the man.
I also still have KISS Meets the Phantom of the Park on Laserdisc because it wasn't available back in the day on DVD. Also have a bootleg DVD of it, but I think it's just a transfer of the VHS. This gem needs a remaster on blu-ray.
Just got done reading Paul Stanley's autobiography, Face the Music, and it was very good. Best of all the members' tell-alls. It's on Audible, too.
EDITED TO ADD: Psycho Circus is the greatest comeback/return-from-a-long-hiatus album in history. Prove me wrong!
