Remember the end of Indiana Jones and the Raiders of the Lost Ark, when the camera pans across a giant warehouse and we know the Ark is in one of those thousands of boxes, but we have no idea which one? That’s what XV’s The Kid With the Green Backpack project has become. Recorded with producer Seven, we know that Green Backpack exists, but no one knows when it will see the light of day. Proof of Green Backpack’s existence arrives today in the form of Losing the Signal, a leak off the project featuring largely live instrument production from Seven, smooth vocals from Jupiter One and rhymes from XV that, among other things, reveal his deep admiration for John Mayer; seriously. I have no idea if/when Green Backpack will drop, and apparently neither does XV, but after listening to Losing the Signal I think it’s safe to say the world’s missing out on some dope music. Keep it locked to DJBooth.net for all the latest.
