Marck-

I've had good success with a sax guy and a pedal steel guy. I had poor success with a drummer/bass player.

A few other guys have had good results with other rythym section pieces...so, its a mixed bag, I'm afraid...

As long as the other two musicians listen and try to compliment what your arranger is doing...theoretically at least...it should be ok...

Good luck-
