This is one of those "documentaries" where the content speaks for itself.  I made this a few years ago, kind of inspired by my own song and music video: "The Complete History of Recorded Music, Part 1".  It's on YouTube, but I'll probably be adding it to VImeo when I open a channel for my band.  It's me playing all the games, too.
