recommendations for a female Russian artist?

[Halla]

for expirimental/ethnic , maybe you should try Sa Ding Ding. she's like the chinese björk. I believe if you can find an active download link in the downloads section for Sa Ding Ding's first international album "Alive".

for Greek , definitely Despina Vandi. just search her name in youtube for samples, tho you probably are familiar with her already. or Elena Paparizou / Antigue, they're were ethno-pop-dance.

you might also want to check out Anggun, she's originally from indonesia or something. but she's had success in europe singing in french & english, her music is ethnic/pop/dance too
