A mix of Rap, Hip-Hop, and R&B. Some of the fastest hardcore songs in the rap game to the most touching lyricists in music today. You're thinking of Bone Thugs

Members
Bizzy Bone - Became a father at 12, molested as a child, kicked out of the group after "Finding God" and having not showed up at numerous shows.

Krayzie Bone - Arguably the most popular/best of the group, was in Chamillionaire's Grammy Winning single "Ridin." Has 1 platinum and 1 gold solo albums.

Layzie Bone - One of the fastest rappers of all time, this high pitched rapper specializes in flow.

Wish Bone - The least known about, non-solo producing bone thug. Deep voiced, and not too good IMO =\

Best albums:
Art of War
E. 1999 Eternal

Songs:
If you're looking for a R&B type song, i'd check out the crossroads. You can find the video here.

If you're looking for a more gangster based song, you should check out Body Rott. You can find the home made video here.

If you're looking for that catchy song that was out last year, check out "Ridin." You can find that video here.

Hope this helps, I reccomend this group to ALL music fans, not just rap.
