There are really great 写真 of キッス with the new tour. We can see how the band members have subtly changed over the years. For close up 写真 of キッス as they are right now, go to link
and check out the 写真 in their slide show. あなた can compare the 写真 to how Gene and Paul looked from 日 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. あなた can see there has been a change behind the masks, so to speak.
Check out the 写真 and see if あなた can tell a difference. Especially the ファン who were the キッス ファン from the beginning.
