It's called
Youthful Funny Voices and it's about dead kids who've been killed by a maniac and are now lying in a morgue.
Not really sure. I mean, all people who listen to Russian rock know them (or at least should know them) along with other "classic" Rock bands of the 80's, and if I had a chance to go their concert I definitely would, but I guess I'm more of an exception. Not everyone's into old-school stuff.
Haha, St. Petersburg's kind of like Moscow in the sense that there's so many very different people you see every day that it's hard to stand out even if you try. However, unlike Moscow, people are more relaxed and friendly there. Even though my mom's from St Petersburg I've only been there once, and I was probably 6 or 8, so I don't think I'd be a good judge of today's fashion there now. It's probably gonna be something else in a week anyway.

Good luck there. Oh, and a piece of advise: bribes. You want something done fast (or done at all), give them a bribe. It's considered a normal thing in Russia.
