Fatboy Slim's classic house anthem is an extravaganza of layering and timbral variety. Bringing it into the world of acoustic a cappella (i.e. possible to sing both without amplification and without looping tech) has all kinds of interesting challenges from both technical and artistic perspectives. We may not have percussion at our disposal, but we can play with a wide variety of vocables to create different sonic textures, and by handing off phrases between singers you not only get the opportunity to manage breathing, but get to create all kinds of fun patterns of interplay.
