Vocalists Tracey Moore and Mercedes Martinez make up Jazzyfatnastees. In 1993, they were part of a vocal quartet that had landed a deal with Tommy Boy. But by 1995, the deal had fallen through. After drifting for a few years, Moore and Martinez found themselves in Philadelphia, their quartet reduced to a duo by departures. The two had known the guys in the Roots for a few years, having opened shows for them in the past.
