During a concert at SXSW last night, Young Guru previewed Kendrick Lamar's remix to “B*tch, Don’t Kill My Vibe” with a verse from Jay-Z.  Check out the preview inside....

Fans of Kendrick Lamar can expect rapper Jay-Z to pop up on a remix to his “B*tch, Don’t Kill My Vibe” off his the good kid, m.A.A.d city disc. It's likely going to be the official remix as Kendrick switched up his first verse and mentioned Brooklyn.  The remix hasn't officially dropped yet, but fans at SXSW in Austin, Texas were treated to a preview of the track courtesy of Young Guru (Jay-Z's DJ).

And in a big announcement made at SXSW yesterday, both Kendrick & Hov will headline during Yahoo's First International Music Festival going down May 3-July 14.  Trey Songz, Frank Ocean, Justin Timberlake and plenty more will also be hitting the stage in cities arond the world.  The fest kicks off in NYC and ends in London.
