4,5,6 is the solo debut by hip hop artist Kool G Rap, released in September 12, 1995 on Cold Chillin' Records. The release followed his break-up with DJ Polo in 1993. The album was mostly received neutrally among critics, but was warmly accepted by underground fans. Despite the album's dark, grimy street sound, it peaked at number one on the R&B/Hip-Hop chart, and the single "Fast Life" charted on the Billboard Hot 100. The album features guest appearances from B1, MF Grimm, and Nas (who also appeared on the front cover), as well as production from Dr. Butcher, Naughty Shorts, T-Ray, and Buckwild of D.I.T.C. It would also be Cold Chillin' Records' final release before it went defunct in 1997.
