Between Bone Thugs-N-Harmony and its offshoot crew, Mo Thugs, the two acts have released more than a dozen studio albums and a sizable number of hits, including “Tha Crossroads,” “1st of the Month,” and “Foe the Love of Money.” But in the eyes of many Bones fans, the best has yet to come. In July 2014, the more than two decades old, Grammy Award-winning G-funk group announced that they were working on their final album, E. 1999 Legends. The double-disc project will serve as a reunion album of sorts, and one disc will consist solely of Bone Thugs tracks, while the other will feature guest appearances from artists like Mariah Carey, Kendrick Lamar, Wiz Khalifa, Drake, A$AP Mob, Phil Collins, and Linkin Park, as well as beats from Dr. Dre. The only downside: Only a single copy of the record will be released, and it will be auctioned off at the starting bid of $1 million. To date, only one single from the album — “More Than Thugs — has been released, and it features the group’s characteristic multi-part harmonies and synth-punctuated melodies. As for the full album, who knows when (or if) it will drop, but, according to Krayzie Bone, there’s at least one fan out there who’s already made a bid on it.
