The main character is trained in classical piano. He's very good with precise tunes. His introduction into Jazz is through a delinquent class mate who plays drums, and the guy criticizes him for not having any swing and emotion. He says that unless you are able to "feel" it, it's not Jazz.
I'm going through the pieces and while I like them just fine, I think that maybe what Trojita is hearing is less of that organic aspect that a lot of classic jazz has. In
Art Blakey's original Moanin', for example, in the beginning piano intro, when Bobby Timmons presses down on the keys there's an individual and unique lightness to each note he presses, which makes it sound very natural and human. The pianist in the Apollon version, meanwhile, sort of plays each note at the same lightness. I'm... not sure if there's a technical term for that, but do you get what I mean? Even his (or her) trills and syncopation seem very deliberate.
Of course, each preview is only that -- a preview, so maybe the songs open up into solos and things like that where the performers loosen up a bit. We'll see. And it's not like they're completely devoid of that "touch"; with Apollon's bassist in Moanin', for example, you can still hear the creak of the wood and the muffled thump of the strings. And the drummer fiddles around smoothly before going into each break with the trumpet.
I hope that made some sense. I like jazz and I play it a little bit, but I'm not an expert by any means so I have very little knowledge of technical terms.
