Kanye West: The recently circulating rumors that he might do just that were confirmed via an “All Of The Lights” inspired video that recapped some of his recent career highlights.The video ends with the words “Austin,” “Vevo Power Station,” “Saturday, March 19” and “11:59PM” flashing across the screen, which are presumably the time and place of Kanye’s performance. He last appeared at SXSW in 2009.
