In 1995, Death Row Records signed rapper 2Pac, and began to position him as their major star: he collaborated with Dr. Dre on the commercially successful single "California Love", which became both artists' first song to top the "Billboard" Hot 100. However, in March 1996 Young left the label amidst a contract dispute and growing concerns that label boss Suge Knight was corrupt, financially dishonest and out of control. Later that year, he formed his own label, Aftermath Entertainment, under the distribution label for Death Row Records, Interscope Records. Subsequently, Death Row Records suffered poor sales by 1997, especially following the death of 2Pac and the racketeering charges brought against Knight.
