From Generation Bass, one of the places I first came across the great DJ Lowdjo (outta Belgium), comes a great example of how political copyright is, and how it tends to hand over power to those in colonial centers (regardless of intention). It also reveals again how Soundcloud is turning on the communities that gave it its start.
So, two American producers (Gonjasufi and Gaslampkiller) release an album that include lots of songs sampling Turkish psychedelic rock songs. Warp records puts out the album. A Belgian DJ (Lowdjo), independently buys the Turkish albums that G&G did, and makes a mix putting those tracks on it. When uploading the mix to soundcloud, it gets pulled for copyright infringement --of the Americans album A Sufi and a Killer.
It's a mishmash of competing rights, communities, and musical practices, and, not surprisingly, copyright law doesn't help use sort out anything meaningful. Although I would be curious to know how far it reaches - who felt the had to or ought to negotiate with whom. I haven't seen the physical album, I don't know if any of the Turkish artists were credited. Or if they were paid.
Coincidentally, Warp records was the only label, back in 2005, to refuse to allow me to include their track on a mix CD I did for Death$ucker records. They said it would cost a flat 200 pounds and refused to negotiate. That was about what I was paid to make the mix of 41 tracks, of which there were only 500 copies ever sold, at I think 5 pounds each. Anyway, I hope they paid 200 pounds to everyone sampled on that record!
And, where did Gonjasufi and Gaslampkiller got the idea to put a song together made from samples? All kinds of people credit the album for its imaginative use of sampling. The idea of doing that, the creative sensibility that informs that practice, comes from the aesthetic of communities that soundcloud first built itself around, and is now divesting itself of (having profited from our participation).
I found the page where Soundcloud debuted discussion of its change in policy and automatic "enforcement" (expansion) of copyright law.. I encourage discussion there as well as here.
