As part of the production of their second album, The xx have set up a Tumblr, where they are sharing their inspirations.
It was here that I came across “Sapphire,” a track from mystery British producer Joe Martin. All I can tell you that he is from Brighton and has two tracks on Soundcloud. There is no more information — he doesn’t even have a picture!
However, if he continues to make electronic music as sophisticated as this, I can’t imagine he’ll stay anonymous for long.
