He co-produced six tracks on Eminem's landmark "Marshall Mathers LP", including the Grammy-winning lead single, "The Real Slim Shady".

He produced the single "Family Affair" by R&B singer Mary J. Blige for her album "No More Drama" in 2001. He also produced "Let Me Blow Ya Mind", a duet by rapper Eve and No Doubt lead singer Gwen Stefani and signed R&B singer Truth Hurts to Aftermath in 2001.
