You know that you have great musicians performing when they have so much command and understanding of what they are playing that they are willing to tell the musical jokes (witty jokes) with subtlety and grace. This is wonderful stuff.
The playing is tight, with the players listening to each other in ways that are too often ignored in larger ensemble pieces. Imitations and joint phrases are actually pulled off like they are in a string quartet. Yes, the Academy is a smaller orchestra that usually performs without a conductor so they are used to ensemble playing. This is just proof that they have accomplished what they set out to do. An chamber orchestra that plays as if it were a single musical instrument with almost endless musical colors and capabilities.
The other two concertos are just as great and fun as the first. There is also a companion disk with 3,5,6, and 7. So, there is even more to enjoy!
