Currently reading Alan Lomaxes - a famous folk song collector and theoretician for musical culture - "Land Where The Blues Began" (and I can recommend it heavily). While searching information about his role in the assembling of the
Golden Voyager Record (I was told that he convinced the committee to reduce the space for classic music in favor for ethnic folk), I stumbled over the
Global Jukebox. Apparently, after the Voyager Disk, Lomax thought about creating a Jukebox that would allow people to experience faraway cultures over their music - it wouldn't work out back then, both for technical limitations and financial issues. 20 years after his death in 2002, a foundation took up the idea and realized it as an online project. I've it running since I discovered it, and it is great - polyphone, multirythmic African choirs take turns with eastern European solists, Turkish sufists, Polynesian singing groups, and Ashkenazi Jews from New York :).
