In 1997, The Flaming Lips released four very different albums that may be played separately or in multiple combinations, but when played simultaneously on four properly synced up players, a beautiful music project named "Zaireeka" is produced.  Fast forward fourteen years and The Lips have decided to find a new way to play their ingenious idea with a different outlet.  Using four iPhones and residing in a bathtub, (which I assume might be for some natural reverb) sync up a couple tracks to demonstrate the aforementioned album.  Check out the video below, get your friends and your smartphones together, and see what you can create.
