In association of the release of his two albums, Art Official Age and the 3rdEyeGirl-assisted Plectrumelectrum, Prince held a lifestream concert with Yahoo! and Live Nation. During his electrifying set, he brought out Kendrick Lamar, as they debuted an updated version of the song 'What's My Name'. Hopefully an official collaboration between the two is on the horizon. Watch this performance below.
