I've made MP3 files of DJ Spooky's preview of his Birth of a Nation Remix (Edited exactly at the beginning and end of the music track that was played along side of his interactive visual presentation so it can be segued accordingly.)

The speaking portion of DJ Spooky's presentation (This is slightly incomplete in that I don't have him saying 'thank you' and making a few comments that he made at the end of the visual part of the presentation.)
