I was not interested in Kiss until a saw the MTV unplugged concert from 1995 ... without makeup btw. And I never thought they are such good musicians. Their performance blew me away and I started to look for more about them... not so much the known songs but the other older songs like I Stole Your Love, Fits Like A Glove, Forever, Rock Bottom, Domino, Plaster Caster and so on. They have some really great tunes which I never heard before. I think they had their best times during the "non makeup" era.
Most of the shows this year were sold out so they must have many many fans out there. Me included. Each to his own.
