The Roots are the coolest band on late night television, holding down the fort on 'Late Night With Jimmy Fallon.' So, it only makes sense that the Fallon returns the favor. The comedian has signed on to host the hip-hop band's 7th Annual Roots Jam Session during Grammy week in Los Angeles on Feb. 12.

Questlove, Black Thought and the rest of the group will celebrate snagging six Grammy nominations for their latest album 'Wake Up' (with John Legend) and 'How I Got Over,' released in June of last year. Sponsored by Hennessey, the event will also coincide with the launch of the organization, Opportunity Nation, which works to "rebuild the American Dream for every man, woman and child," by building a national dialogue regarding economic mobility.

"We're extremely proud and humbled that what began as a simple night to put the focus back on the music has become an amazing opportunity to unite both major artists and new talent in an impromptu musical collaboration," said Questlove. "Unlike many other experiences in the industry today, while also providing a voice to some extremely worthwhile cause campaigns,"

Past performers and attendees have included Legend, Jay-Z, Mos Def and Snoop Dogg.
