De La Soul is an American hip hop trio formed in 1987 on Long Island, New York. The group is best known for their eclectic sampling, quirky lyrics, and their contributions to the evolution of the jazz rap and alternative hip hop subgenres. The members are Posdnuos, Trugoy the Dove and Maseo. The three formed the group in high school and caught the attention of producer Prince Paul with a demo tape of the song "Plug Tunin'".

The group's third studio release, 1993's Buhloone Mindstate, saw the group evolve a new sound as they continued to grow stylistically and musically. There were several moments on the album which proved the band had matured. "I Be Blowin'" was a departure as the track was an instrumental featuring saxophone playing by Maceo Parker. The introspective "I Am I Be" showed De La Soul at their most self-referential to date with subject matter about Pos' daughter Ayana Monet as well as his grandmother. "Long Island Wildin'" was a collaboration with Japanese hip hop artists Kan Takagi (Major Force) and trio Scha Dara Parr (SDP). The album's first single, "Breakadawn", used a sample of Michael Jackson's "I Can't Help It" and Smokey Robinson's "Quiet Storm". De La Soul collaborated for the first time with Gang Starr's Guru on "Patti Dooke", female MC Shortie No Mas, a cousin of Posdnuos, was prominent on many tracks on the album, showcased particularly "In The Woods". The album ended with an old school Biz Markie collaboration called "Stone Age". Missing from vocal duties is Mase, whose voice can only be heard on "Area" in a break near the end of the track. Also rarely featured is his scratching which was heard often on previous albums, with only "In the Woods" showcasing his talent in that area. The album was a critical success, but it was the biggest commercial failure for the group at the time of its release. Many publications, such as Rolling Stone, have listed this album as one of the best hip hop albums of all time.  In 1994, 500 copies of a promotional EP called Clear Lake Audiotorium were released on clear vinyl and CD. The 6 track EP contained edited versions of tracks off of Buhloone Mindstate but also featured the tracks "Sh.Fe.MC's" (Shocking Female MC's) which was a collaboration with A Tribe Called Quest, and Stix & Stonz which featured old-school hip hop artists Grandmaster Caz, Tito of Fearless Four, Whipper Whip, LA Sunshine and Superstar. The EP was widely bootlegged afterwards.  Stakes Is High (1996) was the first album not produced by Prince Paul, with overall production credits given solely to the trio. Although it was met with poor sales, it has been critically lauded for its music, lyricism, and its overall message concerning the artistic decline rap music began to face in the mid-90s. The title track and first single, produced by J Dilla, was not a hit, but the album's second single, "Itzsoweezee (HOT)", with only Dave on vocals, did fare better due to its creative music video. The album spawned a third single "4 More", featuring Zhane which peaked at #52 in the UK. The album did provide a launching pad for future star rapper and actor Mos Def, who appeared on the track "Big Brother Beat". The album also featured collaborations with Common, Truth Enola, and the Jazzyfatnastees.Answer this question using a quote from the following article:
