Wasn't impressed from what I've heard on youtube, Lena has a beautiful voice but these are not the songs to complliment her and they're not to my personal taste. Volkova was a little crude but fair
I'll be waiting to her work with more anticipation, I think Volkova's work will be more Russian and energetic cause Lena's becoming too Americanised, like the Sven Martin personal project or something.
But lets wait and hear the final project when it comes out...
