A great track. I remember when the ad came out I contacted Levis to try and find out who it was by. They never got back to me. Must admit I don't know if it was a song in it's own right that levis used that then got a re-release due to popular demand or if the piece was written for the ad but they then had so many people trying to find out what it was that it was made in to a full song. I know the later is what happened with Stiltskin.
Anyway. The ad.
