I both love and hate the zombie genre. If you can even call it that. When it's done well it's pretty mind blowing stuff... on the other hand when it's not it's just awful violent stupidity.
A while ago I came across this punk band by the name of The Anorexic Olsen Twin. On their self titled LP they have a couple of songs about surviving the zombie apocalypse that I thought were really interesting, particularly the song By the time you read this letter. If you're into really awesome punk music with piano's Violins and cellos you should check it out.
