Delivered on nearly everything. Great use of the economy of instruments. It sure didn't sound like only 8 playing. Shows the marking of true skill.
Loved the Slavic feel to it as well.
I would try criticize, but I fall short of finding things to point out. At the very beginning a few of the instruments sounded out of tune to eachother, and I think a heard a mistake or two. That's it, though.
Everything else was masterfully done. One of the best songs I've heard on the AP for quite a while.
