This is my greatest wish at the moment. I spent one afternoon listening to Duke, Django, Goodman (mostley sextet) and Goodman with Roy Eldridge and Lester Young iirc). There are more than 1.100 tracks to listen to. It is not all jazz there were also fireside chats by president Roosevelt. My listening was cut short when someone came to test Illinois Jacquet's sax. That sound was so loud it drowned out everything else.
