He is credited as a key figure in the crafting and popularization of West Coast G-funk, a subgenre of hip hop characterized by a synthesizer foundation and slow, heavy beats. He was the second-richest figure in hip hop as of 2018 with an estimated net worth of US$800 million. Dr. Dre's solo debut studio album The Chronic, released under Death Row Records, made him one of the best-selling American music artists of 1993. It earned him a Grammy Award for Best Rap Solo Performance for the single "Let Me Ride", as well as several accolades for the single "Nuthin' but a 'G' Thang".
