K, I"ve seen both Motley Crue and Kiss and I can say for a fact that Kiss will blow MC away.
First of all, Vince Neil cannot sing anymore. He's overweight and slow. Get ready to sing alot because most of the singing is done by the crowd. Vince will sing something and then hold the mic out to you! lol It's just sad.
Tommy, Nikki and even Mick, who's like this tiny man, can play the shit out of all the MC songs, past and present, but anything older than the last few cds, Vince cannot sing the fast lyrics anymore. I've seen Motley Crue 4 times since 2000 and it's the same thing everytime.
Kiss on the other hand, are like they were the first time I saw them in 1977. They can still rock and kill every song. Paul Stanley with his new hip, can still do those jumps and wear those awesome high boots. The pyro stuff is awesome.
I'm passing this time, because I'm seeing other bands this summer, but if Vince can change his way of singing or maybe take some oxygen like Axl Rose, then maybe I would consider seeing MC again.
