The Roots' original lineup included Tariq "Black Thought" Trotter (MC) and Ahmir "Questlove" Thompson (drums), classmates at the Philadelphia High School for the Creative and Performing Arts. As they began to play at school and on local streets, they added bassist Josh "The Rubberband" Abrams, who went on to form the jazz group The Josh Abrams Quartet. They later added another MC, Malik Abdul Basit-Smart ("Malik B.") and Leonard Nelson "Hub" Hubbard (bass), and Scott Storch (keyboards). Kenyatta "Kid Crumbs" Warren (MC) was in the band for Organix, the Roots' first album release. Another MC, Dice Raw, joined the band in cameo appearances on later albums. The band filled Storch's position with Kamal Gray (keyboards), who continues in that capacity. Kamal Gray did not play with the Roots on "Late Night With Jimmy Fallon" between April or May and early September 2012. His absence was not publicly explained, however on the September 17, 2012 (NBC's 'Late Night' 700th) episode, Gray returned to the group.
