The first song he co-wrote in that collaboration, "Natural Born Killaz", became a Top 40 hit for Dre and Ice Cube in 1994 (Murder Was the Case Soundtrack).
J-Flexx's success continued when he wrote lyrics for Dre's part in "California Love," a duet with Tupac Shakur.
J-Flexx also co-wrote "Keep Their Heads Ringin," the first single from Ice Cube's Friday (soundtrack) (which ultimately sold over two million units).
On December 5, 2007, it was revealed that For The People Entertainment would be releasing Stayin' Alive a collection of many unreleased songs by J-Flexx from his time on Death Row Records.
This album was confirmed to have featured guest spots from Danny Boy, Sam Sneed, Barney Rubble, The Lady of Rage and Dr.
