Pre-dating Drakes debut, Five Leaves Left, this new posthumous collection, entitled Family Tree, gathers up laid back recordings culled from both Drake originals as well as covers. A few of these (from what I have witnessed personally) have been around previously via unsanctioned bootlegs and file sharing networks. Thankfully the sound here has been doctored and cleaned up considerably.
Look for Family Tree to hit retail shelves in a couple of weeks, and in the meantime download three of the collections tracks below. Also: The excellent Nick Drake documentary A Skin Too Few is available below in three segments.
