Being a trumpet player from origin, I have some reservations.
This solo sounds realy good, for a keyboard.
It will always extremely hard to mimic a true trumpet player (or any other instrument). There are things you can do on the real thing that a keyboard just doesnt mimic right. For example in this piece, all the stacatto pieces sound steril, and are only done in a single stacatto where a real player would use a double.
Still impressive, for a keyboard
