I actually already have this planned out. I'd basically play the entirety of the John Cage and Sun Ra record I have really loud, and then afterwards, karaoke to King Diamond.
EDIT: Also, to whoever said Metal Machine Music, this could easily be substituted for John Cage and Sun Ra. Other possibilities include some Bill Laswell Project (Preferably his thing with MJ Harris, SOmnific Flux) Buckethead stuff (His more... ambient esque works, preferably), Death Cube K stuff, Dead Can Dance, Ephel Duath, Fantomas' Delirium Cordia, That one album I have that has the Dalai Lama on it, Frank Zappa's compositions (Read: NOt his guitar rock band esque music, the weird freak out stuff like Civilization: Phase II and Burnt Weeny Sandwhich), and various John Zorn stuff.
