Query: Top Notch

I got this about 3 years ago and my first impressions were: what a discovery! I couldn't believe my ears! Fabulous, nuanced, graceful, varied dynamics, surprising balance of left vs. right hand in several variations, gentle, elegant phrasing, no show-off etc., etc. and Arte Nova's sound is impeccable - no artificial reverb, no knob-twiddling idiots "improving" the sound. I waited 3 years before I posted this to see if my first "wow" reaction would hold - it does. If you google her name you'll see she is very highly regarded by the few who heard her. I have since learned from a Russian friend that she now concentrates on teaching. Very highly recommended!
