Although I do like Rock Music, I have never understood the appeal of Kiss. I don't like their stage show, all the heavy make-up and most of all I don't really like any of their songs with the exception of "Beth". Beth was a ballad written by their drummer, it doesn't sound like any of their other songs and worse of all for them - it was their most successful song. There is an acoustic version (i.e. unplugged) and an orchestral version. After they sacked the drummer - Peter Criss - they re-recorded with their new drummer.
Having said all that, Gene Simmons was entertaining with his Rock School series - especially in Series 2 where he goes to a comprehensive in Lowestoft and they show him no respect at all.
