This weekend, 2 Chainz headlined the evening edition of the Park City Live concert series during Sundance 2014 in front of 400 fans.

He worked the crowd by opening with his popular Kanye West collaboration “Mercy” and followed with his verse in Nicki Minaj’s “Beez in the Trap." The rapper also performed “Spend It” then “Birthday Song” after asking who was celebrating a birthday that night.

His performance during Sundance was just a rehearsal for his upcoming “2 Good 2 Be T.R.U.” tour which kicks off in February. The rapper said, “I’ve never rehearsed before. This will be the first time I rehearse."
