Through working with Riley, Williams went on to write a verse and help produce for Wreckx-N-Effect's 1992 hit "Rump Shaker". That same year, he also performed a small rap solo on SWV's second hit, "Right Here (UK Remix)". Williams and Hugo met rap duo Clipse in Virginia Beach in 1993, where they were signed to Arista Records through Williams' Star Trak Entertainment imprint. In 1994, Hugo and Williams had established themselves as a production duo under their old name "The Neptunes", and assistant-produced "Tonight's The Night" from Blackstreet's self-titled album. Over the next three years they continued to produce occasionally, and some of the results had little resemblance to the Neptunes' sound later. However, some like Mase's 1997 song "Lookin' at Me" from his album Harlem World, and the most definite beginning of the distinctive "Neptunes sound", came with N. O. R. E's "Superthug" in 1998, reaching number 36 on the Billboard Hot 100, and gaining them widespread attention for the first time.
