Yesterday, DJ Koze released a cut from his upcoming Amygdala double album called "Track ID Anyone?" The title was less a description of music itself, and more a bit of jokey commentary about how confusing the idea of authorship can be in a musical universe that has always sort of been defined by overt forms of borrowing and where the exchange of information seems to accelerate every day. It feels like Koze is daring us to identify his sources, and his nod to the SHAZAAM reflex just makes us realize how far we've come from the days when you could fall in love with a piece of music at a bar or club, and leave the place not knowing whether you'll ever hear it again. Four Tet's Kieran Hebden released a track under the moniker KH last week, and he's outweirded Koze by naming it "The Track I've Been Playing That People Keep Asking About and That Joy Used in His RA Mix and Daphni Played on Boiler Room"—seemingly riffing on the loss of that kind of deeply romantic musical experience, but also hinting at the possibility of carrying the diamond in the rough game straight into the virtual realm. This one's built on a very simple framework of woodsy percussion and delicate breaths, but I dare you to find out where that very awesome African song sample comes from. Pick up a 12" hard copy of the track via Hebden's own Text Records.
