My bandmates and myself all saw Kiss as the ultimate garage band. Simple songs that were fun (and easy) to play, and fun to listen to. Rock that didn't kill a party.
KISS Alive was THE seminal live album. While their studio albums were good, that live album was able to demonstrate their live performance, and it was awesome.
I never did get to see them live... I had tickets to their Destroyer tour, but a family emergency kept me from going to the concert.
