Also, I suggest you get stoned. It couldn't hurt. Besides it'll help you get into the party more.

Everyone loves a stoner!

truncated knows her shit.

but if you want a surreal party, get deerhoof's entire discography and get as much spazztic japanese music as you can, and turn it up really loudly. the party will have a feel like everyone's on acid without the acid.

you can also substitute the musical choices with death metal and grindcore, that gives a different but still fucked up effect.

also having all your guests dead drunk help.

If you want to play really safe go for:
Electronic1-various(rough trade)
It cant fail to have your inebriated guests entertained and their butts will need a good rest for a while after that
