While we’re used to featuring elusive and masked artists here at XLR8R, it’s not often that we come across one-off, undisclosed collaborations. NN, a mysterious duo that might very well hail from somewhere in Europe, is one such pairing, and has shared a track it made for the second compilation from the Polaron Collective, Selections #2. Simply called “001,” NN’s production is a shuffling and melodic tech-house number that features dreary, shapeshifting pads and a smoothly grooving bassline. If you’re feeling “001,” be sure to look out for the rest of the compilation when it drops on October 29.
