This is quite awesome actually. Hans Zimmer, the composer of TDKR score and almost every other awesome movie score out there, wants you to add your voice to a worldwide chant which is being created for TDKR. I don't know how it exactly it fits in, but I love the idea of getting the fans involved. All you need is a computer with internet and a microphone, and you can be part of history. This epic undertaking is being run through Ujam, so just go there to let yourself be heard!
