On the other hand, there existed an alternate genre of hip-hop, composed of the middle class, referred to as conscious hip-hop. This genre focused on political consciousness, positivism and afro-centricity, and was largely critical of the gangsta-rap culture. Conscious hip-hoppers berated the gangsta-rappers, claiming the genre was a bandwagon, that they were invested in image over lyricism, and that it was a means to project grief and negativity back onto the culture.
The group A Tribe Called Quest was the most prominent of the conscious hip-hop genre throughout the 90s (such as groups like De La Soul, Public Enemy, the Roots etc.). Although gangsta-rap was gaining immense popularity, conscious hip-hoppers focused more on advancing their particular genre, and experimenting with different techniques, lyrical and musical styles, etc.
The most significant of these advancements is certainly A Tribe Called Quest's incorporation of not only samples of early African-American jazz music, but also a jazz musician himself. Ron Carter, and African-American jazz double-bassist was hired for the recording of the group's 2nd album, The Low End Theory. Ron Carter, whose 50 year career had lined him up with artists like Miles Davis, is historically the most influential jazz artist of the conscious hip-hop genre because of his creative collaboration with the group. He plays bass on the track "Verses from the Abstract" and at the end of the song, Q-Tip gives him a shout out. The song, "Jazz (We've Got)" samples early 60s jazz artist, Lucky Thompson's "Green Dolphin Street." The album cover for the single of that track emulated the famous Blue Note Records logo style, a prominent EMI label producing strictly jazz music.
The function of jazz in hip-hop music has been defined by A Tribe Called Quest. It serves to fuse African-American music from the past with that of the present-providing for a musical conversation of multiple genres within one. Hip-hop was certainly the dominant form of popular music in the 90s, just as jazz was in the 20s and 30s. Jazz-infusied hip-hop pays tribute to the former genre and reinvigorates and advances the latter. Ron Carter's appearance on The Low End Theory is indicative of expansion and experimentation of the genre due to supremely creative ideals, production methods, and above all, collaboration.
