Video: Jay-Z "PSA" Live At Carnegie Hall

More house-rocking footage from Jay-Z's February performance at Carnegie Hall with NaS and Alicia Keys. White Casino Royale tux and shades, 10-story flag in the back and full orchestra (see if you can spot the Questo) playing "PSA"--oh, I think he did come here to show out. This comes of course right on the heels (Louboutin, I suspect) of the announcement of Hov's SXSW show, also sponsored by AmEx.
