Ok, a few more pages are online now, i can see that the guy who's making that site has the same working hours as me! LOL
Here, you can see the list of the artists on the Podnebesnaya album.
It's worth noticing that while every artist has a picture of their face and a detailed page about them, Tatu only has an old picture framed on Lena's chest and a cartoon making fun of the situation with the girls... odd, to say the least.
And again, it's only Lena, in the picture and the cartoon.
