In the mid-1980s, years before Wu–Tang Clan was founded, Cousins GZA (then known as the Genius), RZA (then known as Prince Rakeem), and ODB (Ol’ Dirty Bastard, then known as Ason Unique) were all making music under a trio originally named Force of the Imperial Master which later became known as All In Together Now Crew. The group ended up dissolving and in 1992 the nine-member Staten Island group Wu-Tang Clan was formed and the group consisted of RZA, GZA, Ol’ Dirty Bastard, Method Man, Raekwon, Ghostface Killah, Inspectah Deck, U-God, and Masta Killa.
The following year Wu-Tang Clan released their debut album Enter the Wu-Tang (36 Chambers). All in Together Now never released an album as a trio.
