Danito,

KISS, in my opinion, is not an exceptional musical act. Though I do believe that they are the masters of 'arena rock' (whatever that is), I've never been a big fan of theirs. However, I think it would be hard to argue that they haven't played a massive role in the evolution of the live show; transforming a gig into a concert, a performance.

Kiss's live album 'Alive!' has also left its mark on music history. Besides being one of the biggest selling live albums of all time, it re-popularized the live album in the mid 70's.

Regardless of your feelings on their music, you have to give them credit for being the most recognizable band in the world!
