Bone Thugs-n-Harmony is an American hip hop band from Cleveland, Ohio formed in 1991. It originally consisted of rappers Layzie Bone, Flesh-n-Bone, Bizzy Bone, Krayzie Bone, and Wish Bone. Rapper Eazy-E of the group N.W.A signed Bone Thugs-n-Harmony to Ruthless Records in late 1993, when Bone Thugs debuted with EP Creepin on ah Come Up. The EP included the hit single "Thuggish Ruggish Bone".
In 1995, the group released its second album, E. 1999 Eternal, which included hits "1st of tha Month" and "Tha Crossroads." A tribute to the recently deceased Eazy-E, "Tha Crossroads," won a Grammy award in 1997. The Art of War, the group's third album, was also released in 1997. Bone Thugs is also the only group that has worked with deceased artists 2Pac, The Notorious B.I.G., Eazy-E & Big Pun while they were still alive.
