Last night, Kanye West held another listening session for his upcoming Yeezus, this one in Basel, Switzerland. During the event, Kanye took a moment to perform an impassioned and ferocious a cappella version of his “New Slaves,” a rendition that made it impossible to deny how powerful his verses are. Following that, Yeezy took to his laptop to play the audience his track with Daft Punk, “On Site.” Check out fan footage of the performance above.
