A few hundred fortunate souls got to see a live performance by Kanye West and Jay-Z over the course of SXSW Musical Festival earlier this year. Today, that performance, featuring the single "H*A*M*", went live on the VEVO online video channel. A taste on what's to come from "Watch The Throne", the forthcoming album between both artists, "H*A*M*" is obscenity laden, forceful declaration on their point of views. As summer chug along, expect more singles and joint performances to come. Or you can watch West and Jigga light up the stage after the jump.
