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 originated in Philadelphia with Ahmir "Questlove" Thompson and Tariq "Black Thought" Trotter while they were both attending the Philadelphia High School for the Creative and Performing Arts. They would busk out on the street corners with Questlove playing bucket drums and Tariq rapping over his rhythms. Their first organized gig was a talent show in 1989 at the school where they used the name Radio Activity, which began a series of name changes that progressed through Black to the Future and then The Square Roots. In 1992, they dropped the "Square" because a local folk group had claim to the name.  Organix was the band's first album, released and sold independently in 1993. It drew offers from music labels, and the band signed with DGC/Geffen. The Roots' first album for DGC, Do You Want More?!!!??!, was released in 1994. It was a moderate hit among alternative music fans, boosted by the group's appearance at Lollapalooza. The band performed at the Montreux Jazz Festival that year. Touring guests, beatboxer Rahzel and producer Scott Storch, joined The Roots.  The 1996 release Illadelph Halflife was the group's first album to break the Top 40 on the Billboard 200 chart, spurred in part by MTV's airplay of the video for "What They Do" (a parody of rap video cliches) and "Clones", which was their first single to reach the top five on the rap charts. "What They Do" was also the group's first single to hit the Top 40 of Billboard's charts, reaching a peak of #34. While continuing on the path of live instrumentation, the album's sound was somewhat darker. Answer this question using a quote from the following article:
