Bassist/singer/songwriter Aaron Mills’ first professional tour was with Chuck Jackson. Mills also recorded some songs with Willie Hobbs, which piqued his interest in session work. He came to Durham to join trumpeter Donald Byrd, who assembled New Central Connection Unlimited, a funky jazz ensemble. The group toured for a year and shared bills with Cameo.
After New Central Connection Unlimited disbanded in 1978, Mills joined Cameo as its bassist. After five years in Cameo, Mills left in 1983 to form MCB with Cameo keyboardist Tommy Campbell and trombonist Jeryl Bright. After MCB, Mills recorded a few singles for Sylvia Robinson's Sugar Hill label and eventually rejoined Cameo in 1985.
In 2000 Aaron and Cameo's sound engineer Shy Boy ended up in the studio of OutKast to record a bassline for "Ms. Jackson" and "So Fresh, So Clean." Since then, Mills has played bass for eight other tracks on "Stankonia" and "Speakerboxxx/The Love Below”. Mills briefly toured with the group and gave Andre 3000 bass lessons. His connections through Organized Noize producer Rico Wade led to sessions on Cee-Lo Green, Bubba Sparxxx and Gwen Stefani recordings.
