I'm glad you liked the track. Robert actually strung together the listenable bits from two different gu zheng improvisions. I had tuned the zheng to an unconventional scale that seemed to fit with the mood of Robert's backing tracks. I don't think I would have the chops to sustain that kind of mood for an entire album. Thanks for the encouragement, though. I prefer to work with a "multiple instruments" sound anyway--a lot of layering. I did recently play a short zheng solo as part of an extended piece that should be appearing on my next album. I'm not sure how the CD was received by others, but I liked it a lot and it's definitely one of my favorites of Robert's releases.
