Arnett Howard is producing a fascinating archive of African American music on his site.
Here is his vision:
"It is my legacy to inspire children to play instruments early in their lives. It can be done in a number of different ways; bringing them to the microphone to sing along, teaching them how the trumpet works and letting them try, even helping them to write a song and make a compact disc recording of their works."
You can find a wide range of material on his site across all genres of African American music over the last 100 years with some wondeful photographs.
