Bone Brothers is an American hip hop duo composed of Bone Thugs-n-Harmony members Layzie Bone and Bizzy Bone. The first Bone Brothers album was released in 2005. Bizzy Bone had parted ways from the group in 2003 over personal differences and business decisions. Bizzy Bone had always remained friendly with the group and collaborating in songs such as Lil Eazy’s This Ain’t A Game and Krayzie Bone’s Getchu Twisted Remix. The Bone Brothers track Hip-Hop Baby contains all four members in the music video. In 2009 the whole group came together to record tracks for Uni5: The World’s Enemy during the wake of Flesh-n-Bone, the previously unofficial fifth member’s return from prison. Bone Brothers is an album series and not a name for Layzie Bone and Bizzy Bone collaboration albums. Albums like Still Creepin On Ah Come Up are excluded from the series. It is also conceivable of any pair or more Bone Thugs-N-Harmony members making a Bone Brothers album in the future.
