In March 2009, the Grammy-winners became the house band on NBC’s Late Night With Jimmy Fallon. In 2012, Questlove announced that hip hop's legendary band was working on their 11th studio album, titled & Then You Shoot Your Cousin, which Black Thought confirmed would be released May 2014 via Twitter. Along with Jimmy Fallon, The Roots moved toThe Tonight Show in 2014.
