Esham is a Detroit rap legend. He has released tons of records and he has a totally original style. He was born in NY but moved to Detroit while he was a kid. There he started developing his own rap style which he called Acid Rap. It is some kind of gangsta rap with lots of violence, but with an old school NY way of rapping. I remember I thought his early records were like Beastie Boys with gangsta lyrics. Anyway, he developed the Acid Rap style during the early 90s to something you won't hear anywhere else and has released lots of records, alone and together with his group Natas. His debut album came in 1990 and was called Boomin Words From Hell. He first released in on tape only but then re-released it on CD. If you are looking for something truly original, which you may find to be either very good or terrible, you should check out his records. I would recommend: Boomin words from hell, Closed Casked, KKKill the fetus and Mail Dominance. He got top score in Murder Dog for both Mail Dominance and Natas'
WWW.com a couple of years back. And by the way, Eminem has rated Esham as his main influence but they had beef some years ago resulting in someone in D12 beating him up.
