Check out Do or die. For example Do You and Twista is on that song with them. That whole album is one of my favourite all time. They have/had a singer named Johnny P who sings crazy good r&b vocals but he has unfortunately passed away. Also check out Bubba Sparxx album called Deliverance. Timberland made the beats for the album before he got world wide famous. And for fun check out Timberland and Magoo. Timberland was in a duo group with Magoo and made the beats for them and you can hear right away that he is the best beat maker out there.
If you check it out then please let me know what you think :)
