Why did drdre leave nwa?

Dr. Dre left N.W.A in 1991 primarily due to creative differences and financial disputes with other members of the group, particularly Eazy-E and their manager, Jerry Heller. He was also seeking to pursue a solo career and wanted more artistic control over his music. Additionally, he was frustrated with the group's volatile dynamics and the negative impact of their lifestyle on his personal life. This decision ultimately led to the founding of his own label, Death Row Records, and the release of his iconic album, "The Chronic."
