This may not be jeans, or even in a great pun, the new blues. But, heritage denim label, Levi's is on to something interesting with the new Pioneer Sessions campaign. For this campaign, Levi's enlisted the help of 12 important names in music across different genres ranging from hip-hop to pop, from rock to soul... to cover a classic track in their own signature style. First up is rapper Nas who had taken on Slick Rick's "Hey Young World", which Nas commented was a song everyone can relate to. The tracks are available for download at Levi's, so check out the video, the track, and store it on your iPod.
