Kanye West exhibited his musical masterpiece, performing at the 2011 MoMA Party in the Garden Benefit at The Museum of Modern Art in New York City last night. Dressed casually in a gray hoodie and ripped jeans, Yeezy mixed art with the sounds of his critically-acclaimed album My Beautiful Dark Twisted Fantasy before a well-dressed crowd of 1,000 attendees.

“For most of the 45 or so minutes that he’d been onstage, Mr. West had been moody, dour, even irritated at points, a star who enthralled even at low wattage,” wrote The New York Times, which also noted his “harsh” cover of Stevie Wonder’s “They Won’t Go When I Go.”

But his mood changed when big brother Jay-Z joined him onstage for the finale of “H•A•M” and “Empire State of Mind,” putting a smile on his somber face.
