I started watching this on Hulu today. It only has 10 more days on Hulu and it’s being pulled, and I have no idea where you would watch it then. It presents music at a nut and bolt level, with great stories as an example. For instance there is an episode about the changes electricity has made to music. It starts with how the guitar player in the big band era went from being a rhythm player to being a soloist, simply because you could hear him now. It then takes it all the way through synths and beyond.
If you want to see how some great music was made I would recommend this.
