There are really great चित्रो of किस with the new tour. We can see how the band members have subtly changed over the years. For close up चित्रो of किस as they are right now, go to link
and check out the चित्रो in their slide show. आप can compare the चित्रो to how Gene and Paul looked from दिन one, and see that even though they wear the same make up, they look different with it than they did when they first started out. आप can see there has been a change behind the masks, so to speak.
Check out the चित्रो and see if आप can tell a difference. Especially the प्रशंसकों who were the किस प्रशंसकों from the beginning.
