Alright, the project is set up and ready to go.  Tomorrow morning during Tom's 4th grade band rehearsal, Josh and I are going to listen in on the rehearsal via ichat.  We set up two professional cardioid recording microphones to pick up the sound of the band.  The signal will pass through a midi interface module into the usb port of Tom's computer at the elementary school.  At the same time Tom will run Garage Band on his computer to make a recording of the entire session which we can edit and place on the elementary band blog for comments from the band members.  While the band is playing, Josh and I will be over at the middle school watching and listening to the performance with ichat.  We'll patch the computer to the stereo to give us the highest quality reproduction.  After they play, we'll comment on specific elements of their playing directly to the students in real time so they can reflect and even ask questions.  Also, the students will have an opportunity to listen to the recording and comment on aspects of their performance that we have discussed.  We'll apply the same process with my 7th grade band on Monday the 26th and Josh's Symphonic (11/12) on Wednesday the 28th.  It actually seems like it will work out well and will hopefully be something we'll set up with band directors from other districts.
