The sonics have some great songs that would go well in a halloween party type environment... Strychnine, Psycho, the witch, he's waiting... This is garage rock from the 60s think Kinks, or the kingsmen (louie louie) but with darker themes...

the misfits have been mentioned on various threads here, and no doubt a good choice, but i think Danzig's other band Samhain is a much better choice...
