While this is few months old, I literally just found out about it and it... made me happy. Something very nice of Pretty Lights!
....Pretty Lights has released a collection of rare, and unreleased tunes into the hands of fans in the form of USB 2.0.
As the “Pretty Lights Movement” project continues to evolve, the idea of getting old and rare tunes to the fans as a way to progressively collaborate, bring the entire community together, share art in a different format, and move these rare pieces of sound forward to the social media platform also continues to evolve.
