Wu-Tang Clan is an American hip hop group from Staten Island, New York City, originally composed of East Coast rappers RZA, GZA, Ol' Dirty Bastard, Method Man, Raekwon, Ghostface Killah, Inspectah Deck, U-God and Masta Killa. Cappadonna later became an official member of the group. The Wu-Tang Clan has released four gold and platinum studio albums. Its 1993 debut album, Enter the Wu-Tang (36 Chambers), is considered to be one of the greatest albums in hip-hop history.

All in Together Now was never signed to a record label. See, me, GZA, and ODB had a crew called FOI: Force of the Imperial Master, nah mean? We made a song, called "All in Together Now", which became famous on tapes throughout Brooklyn, Downtown Staten Island, New York, all the way down to Miami. I remember Biz Markie, when he was famous and I wasn't famous, and he was like: "Yo! I heard that shit! Your song with Ason Unique and The Specialist." I was the Scientist. So we never got signed as a group back then. We never had a serious record deal under that title. The Wu-Tang Clan was assembled in the early 1990s with RZA as the de facto leader and the group's producer. Method Man - who met RZA in 1990 after hearing a tape the producer recorded as Prince Rakeem - recalled: I went round his house. We went to the basement and I guess they was showin' off 'cos I was there. There'd be RZA and his brother Devon on the decks. RZA was cuttin', Devon'd go cut off the light, then RZA's go cut on the light, Devon'd be cutting, then he'd go cut off the light. They was doing some wild shit, man. And Ol' Dirty was there and he'd echo every rhyme of RZA's while beatboxing, 'cos that was in style then. That was the beginning of Wu-Tang. RZA and Ol' Dirty Bastard adopted the name for the group after the film Shaolin and Wu Tang. The group's debut album loosely adopted a Shaolin vs. Wu-Tang theme, dividing the album into Shaolin and Wu-Tang sections. The group developed backronyms for the name (as hip hop pioneers such as KRS-One and Big Daddy Kane did with their names), including "We Usually Take All Niggas' Garments", "Witty Unpredictable Talent And Natural Game", and "Wisdom of the Universe, and the Truth of Allah for the Nation of the Gods".Answer this question using a quote from the following article:
