Here is the rephrased text:
Fredro Starr, a renowned rapper, was an integral part of the pioneering hip-hop group Onyx, which made its debut in 1993. This talented trio made a significant impact in the music industry, as they won Soul Train's prestigious Best Rap Album of the year award in 1993, beating out Dr. Dre's highly acclaimed album, The Chronic. Unfortunately, Fredro has officially retired from his rap career, opting instead to focus on his burgeoning acting career, which has spanned an impressive decade. Despite releasing two solo albums in recent years, they received lukewarm reception, failing to garner significant attention or acclaim.
As for his early beginnings, Fredro was discovered by the legendary hip-hop group Run DMC and the late Jam Master Jay in 1989, setting the stage for his future success in the music industry.
