The DVD, or rather, DVDs for Chris Rock's 2008 HBO special, Kill the Messenger, became available on Tuesday. You can experience the special as it aired, or get the full package, as it were, with a three-disc collection that includes all three performances separately from Johannesburg, London and New York City, plus extra goodies. In this clip, Rock explains what he was going for, something original and global, and how U2 provided inspiration in Rattle & Hum.
