Which Russian musicians do you know/like?

Never heard of a single one surprisingly! Could anybody be kind enough to suggest me some..?!

I know: modern Tatu, ppk and some of the componists but not by name.

PPK?

Tchaikovsky, Mussorgsky, Stravinsky, Shostakovich and Rachmaninoff I like the best... But also Borodin, Glinka, Prokofiev...
