I have seen them several times, the “Brothers in music”. It’s just the type of minimal deep tech house music I love. Flirry, minimal, a little melancholic and driving. Check out their beautiful website Brothers-in-music.de
They just released a 4 Track EP, you can listen to the tracks and download live mp3s. I read about it because they released the EP under a Creative Commons license.
To the knowledge of Netzpolitik it is the first vinyl record with a CC license. I guess, it won’t be the last.
