The Wu-Tang Clan attended the Sundance Film Festival this year to promote their new docuseries Of Mics and Men, and on a visit to the Vulture Spot video studio, group member Ghostface Killah walked us through that time he ended up on 30 Rock. When the legendary hip-hop group assembled decades ago, who could have foretold that one day Ghostface would be slinging Donaghy Estate Sparkling Wine and performing alongside Jenna Maroney. Fame is a funny thing.
