If you're anything like Rocks Off you're worried about two things: a) That jars of olives are somehow sentient and plotting our demise; and b) that when the dead rise and life becomes a bitter struggle between the living and the zombies there will simply be no time left for music.
Thanks to one man, Christopher Michael David Herron, we no longer have to worry about such a thing. Herron was inspired by a contest to produce a musical instrument out of garbage or trash - the contest's administrator, a morbidly obese man named Albert, could not be reached for comment.
Herron decided that he would utilize what will surely be the most common objects post-World War Z, namely the spent shell casings dropped by desperate defenders before the ghoul hordes pull them down. The result is a fully functional pan flute, and Herron has even been able to pull off Beethoven's "Ode to Joy" using the instrument.
Clearly, we're dealing with a prophet and a genius, so Rocks Off fired off some emails to Herron's hollow volcano lair in Colorado to question him further about the music of the future wasteland.
