A well recorded jazz disc with some complex and interesting music. Lots of synthesized sounds make this something out of the ordinary -- if you're a fan of electronica you may enjoy it. I agree with Beached in that some tracks make better use of the surround channels than others. My ears vote 8.
Excellent sonics and musicianship. Most of the tunes are piano trio with the band to the front and ambient 'verb in rears. However the few tunes with synth are more adventurous with the synth actively hopping about. I think all the mix choices are effective and appropriately serve the music. She's quite a versatile and adept composer as evident from the contrasts in style from track to track. And, of course, a brilliant improviser and technician. The opening track (Kung-Fu World Champion) is the standout for me. 9
