The group was led by emcee David "Redhead" Guppy (an actual redhead), who also played keyboards. The F.B.I. consisted of Joseph "D.J. Wildstyle" Mann, Bo Roc, Lt. Squeak, Buzz, and Poochie.[3]
A Shade of Red contained two other singles, "Pump It, Hottie", which reached No. 2 on the US Hot Rap Singles Chart in 1990, and "We Rock the Mic Right". The album was produced by Redhead and Markell Riley from the duo Wreckx-N-Effect (the younger brother of producer Teddy Riley) and was heavily influenced by the new jack swing trend at the time.
In 1991, the group released its second and final album, The Album with No Name.[4] Recorded at Hillside Studios, Englewood, New Jersey, and Soundtracks Studios, New York, The Album with No Name peaked at No. 182 on the Billboard 200, while the song "3-2-1 Pump" reached No. 52 on the Billboard Hot 100.[5]
The group also appeared on a track of the soundtrack of the 1991 film New Jack City. That same year, Guppy made his acting debut in the film Strictly Business, which also starred Halle Berry.[6]
In 1993, Redhead Kingpin returned with Gicci Brown, D.J. Wildstyle, and Knowledge to form a new group called Private Investigators.[1] Private Investigators had a harder-edged hip hop sound, and released one album titled React Like Ya Knew on Virgin/EMI.[8]
