Jay-Z performed “Roc Boys (And the Winner Is)” on the Late Show with David Letterman last week.  “Roc Boys” is a joint off of his latest (concept) CD American Gangster which is in stores today.  Expect to see big numbers off of this.

Jay’s performance was pretty flawless.  He was his usual self, rockin’ the mic with ease.  But the ear-catcher is the performance by the band, especially those dudes on the horns.  They tore it up!  I’m assuming  these are the same cats that will go on tour with Jay later this month?  If so, that’s what’s up.
