The Soulquarians were a rotating collective of experimental Black music artists active during the late 1990s and early 2000s. Initially, they were formed by singer and multi-instrumentalist D'Angelo, drummer and producer Questlove, and producer-rapper J Dilla. They were later joined by singer-songwriter Erykah Badu, trumpeter Roy Hargrove, keyboardist James Poyser, singer Bilal, bassist Pino Palladino, rapper-producers Q-Tip and Mos Def, and rappers Talib Kweli and Common. Prior to its formation, Q-Tip, Common, Mos Def, and Talib Kweli were members of the Native Tongues collective, whilst Q-Tip's original group A Tribe Called Quest served as one of the inspirations behind the Soulquarians.
