Just discovered this band recently, thanks to GTA4, and I think I'm in love with it. I don't speak the language, but every time "Schweine" came on
the Radio in the game, I'd stop what I was doing and listen to it.
Then I found the music video on youtube.
Then I found another music video with the actual singer in it.
Then listened to some of their other stuff, and still like them.
It's a very different sound, even for Russian I think.
Some other Russian artists you might enjoy would be t.a.t.u. and Nichya. Not quite in the same vein as Glucoza, but good nonetheless. Very strong
female vocals (not nasally like Glucoza).
Unfurtunately there is a seemingly endless wealth of sucktastic Russian music and videos out there, but these 3 are definite highlights.
