No, the band which plays on "Late Night With Jimmy Fallon" is The Roots, a hip-hop group formed in 1987 by rapper Black Thought (Tariq Trotter) and drummer Questlove (Ahmir Khalib Thompson).
One of the most prolific rap groups, the Roots were also among the most progressive acts in contemporary music, from their 1993 debut through their conceptual 2010s releases. Despite the seemingly archaic practice of functioning as a rap band with several instrumentalists -- from 2007 onward, their lineup even featured a sousaphonist -- they were ceaselessly creative, whether with their own material, or through their varied assortment of collaborations.
Nappy Roots is an American alternative Southern rap quartet that originated in Bowling Green, Kentucky in 1995. They are best known for their hit singles "Po' Folks", "Awnaw", "Roun' The Globe" and "Good Day". They were the best selling hip hop group of 2002.
