This is an arrangement of "Wave" (Jobim) for trombone group and rhythm section.
They are the last semester trombone group of EMESP (Escola de Música do Estado de Sao Paulo, Brazil, or "São Paulo State School of Music").
The trombone teacher / group leader invited the rhythm section to play with them on the recital, was funny.
I was using a Fishman BP100 pickup and amp was a Roland Cube 60watts , the result was surprisingly not bad, as I don't love the BP100. However hearing from the amp on the stage was not as good as it is sounding through the video.
Hope you enjoy. http://youtu.be/519qesZgl5Y
