Question: The Roots is an American hip hop band, formed in 1987 by Tariq "Black Thought" Trotter and Ahmir "Questlove" Thompson in Philadelphia, Pennsylvania, United States. The Roots are known for a jazzy and eclectic approach to hip-hop featuring live musical instruments. Malik B., Leonard "Hub" Hubbard, and Josh Abrams were added to the band (formerly named "The Square Roots"). Since its first independent album-length release the band has released 10 studio albums, two EPs, two collaboration albums (with other artists), and also collaborated on recordings and in live shows with a wide variety of artists in many musical genres.

The Roots' original lineup included Tariq "Black Thought" Trotter (MC) and Ahmir "Questlove" Thompson (drums), classmates at the Philadelphia High School for 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. Beatboxer Rahzel was a band member from 1995 to 1999. Alongside Rahzel was turntablist/vocalist Scratch, who also DJ'd in live concerts. However Scratch left abruptly in 2003. Malik B. left the group in 1999 due to personal reasons but continued to record, making occasional cameos on some albums. Guitarist Ben Kenney, had a brief stint with the group and contributed to the Phrenology album, but left to join Incubus as bassist. Percussionist Frank Knuckles joined the lineup in 2002 and guitarist Kirk "Captain Kirk" Douglas replaced Kenney. Vocalist Martin Luther toured with the Roots in 2003 and 2004 and contributed to the Tipping Point album. The group announced in August 2007 that its longtime bassist Leonard Hubbard was leaving. Owen Biddle was the band's bassist in 2007-2011. The band announced on August 25, 2011 that Owen Biddle left the band, replaced by Mark Kelley. On The Tonight Show Starring Jimmy Fallon, James Poyser plays additional keyboards. Because most of the band members hail from Philadelphia and its surrounding area, they showed their support for the Phillies during the 2009 World Series against the Yankees, displaying Phillies memorabilia when performing on Late Night with Jimmy Fallon. On the episode which aired the day after the Yankees clinched the title, Questlove stated "No comment!" on the show's intro (when he usually states the episode number), and had a Yankees logo purposely displayed upside-down on his drumset. In 2010, the group showed support for the Flyers during their run to the Stanley Cup Final by having the team logo on their drumset, and again in 2014 when the Flyers faced the New York Rangers in the first round of the playoffs on The Tonight Show Starring Jimmy Fallon. In April 2017, Frank Knuckles left the Roots due to family issues, and has not appeared on The Tonight Show since then. Later in August 2017, Knuckles sued Questlove, Black Thought and the band manager Shawn Gee over unpaid royalties. In June 2017, Questlove announced in an interview that producer and performer Stro Elliot is an official member of the Roots.
