I'm glad to see this post. Dave is one of my favorites here. This is a great example of the differences between arranger play and real interaction between people "playing" off of each other.
Night in Tunisia is a great tune to illustrate the difference because of the abrupt tempo change...one of the classic tempo changes in contemporary music.
The arranger is a good example of excellent musicianship AND the differences mentioned above.
Sadly, today, economics, personality conflicts, available jobs, etc. make totally live group play impractical, sometimes, and, frankly, a Pain in the A** other times.
But, "ain't it GREAT"?
Good work, Dave!
