Choir in Kiev? (Kyiv)

Dear friends,

Has anyone of you come across a young choir (english, russian, ukrainian - all fine) in Kiev that you could recommend? Nothing too professional (rehearsals once a week) but with some ambition, young people and an interesting, mixed repertoire (classic, modern...) Any hints would be very welcome - particularly from the Kievans here :) Thanks a lot!

Cheers
Martin
