Dr. Dre
Before he was making Beats by Dre, Dr. Dre was known for, well, beating up people when he was a part of Death Row Records. Aside from his crew’s infamous violent antics, Dr. Dre famously attacked television host Dee Barnes. But after the fall of Aftermath and the death of friend, Tupac Shakur, Dre slowly but surely left his chaotic Gangsta Rap past behind to become a calmer business man and music maestro.
