Argos, how can you not like Eva Polna ?! There is something about her voice and it's nice not to see someone like a stick insect ! Not done too badly on tophit.ru either. Granted her latest vid isn't that exciting but I loved this ... (and I'm not 50 lol)

Svetlana Loboda also seems OK but I don't know much about her. My friends here enjoyed the song/vid Облака.
There are some good alternative groups around in Russia and some of the older bands have released enjoyable songs last year. Goth (ish)/industrial/ebm can also be found if you look a little harder. Checkout a band called Scofferlane, they sing in English. Something a bit different for you ! And here ends my fleeting Tatysite visit
