This is not really a music video per se, but it's so cool I had to post.
Tony Monaco, hammond organ player extraordinaire, gives the most concise explanation I've ever seen of all the awesome things about this legendary instrument. With a performance! Tony is also the most willing and prominent educator for this instrument out there, as far as I know.
Yesterday, I emailed him and told him my goal was to play the hammond organ as if I were mimicking a big band (count basie, to be specific). He put this video up less than a day later. I had initially told him I was interested in his drawbar settings, since I've known he goes through the trouble of rewiring everything to his liking. I was blown away by this. He makes tons of references to big band stuff, even basie's guys. What a generous man.
