That EWI solo is awesome. It's a synth... except a clarinet.
This is movement one of a ridiculous modern jazz piece by Adam Neely, the coolest jazz bassist online (he plays, among other things, a Fender jazz)
The third movement is, according to Adam, a metal song written for jazz band.
And the resolution in the fifth movement is gorgeous.
You'll have to check out movements 2 and 4 yourself. The live performance that they recorded is all online, including the encore, "hey man have you checked out meshuggah's new album yet?"
