Guy was a popular 1980s and 1990s hip-hop, R&B and soul band that was one of the early pioneers of hip-hop/R&B music and which set a trend in the early 1980s in a movement called the New jack swing.
Formed in Harlem, New York in 1987 by young musician/record producer Teddy Riley, the original members of Guy included Riley and R&B singer-songwriters Aaron Hall and Timmy Gatling, who were students at HBCU Virginia State University in Petersburg, Virginia. After signing to Uptown Records, the group released their first self-titled album in 1988. Gatling left after the first album was done and was quickly replaced by Aaron's younger brother Damion. Upon its release, the album went platinum three times over and included the hits "Groove Me", "Teddy's Jam," "I Like", "Piece of My Love" and "Merry-Go-Round of Love". That first album quickly established the group and Riley as musical forces.
After producing music for other artists ranging from Bobby Brown to the Winans, Riley returned to Guy for their second album, The Future, in 1990. The songs "I Wanna Get Wit U" and "Let's Chill" gave them a broader, mainstream fan base. However, Riley's other work basically kept the group out of the studio for the rest of the decade. Both Aaron and his brother Damion recorded solo albums, Aaron being a major influence on the style of R&B singer R. Kelly.
In 2000, Riley and the Hall brothers reunited to release their first album in nine years titled Guy III. The album featured the modest hit "Dancin'", but their label MCA Records had a hard time promoting it. As quickly as it was released, it quickly dropped from the public radar. Since then, Guy has been relatively quiet, but rumors of working on a new album still linger.
In 2006 they were part of New Jack Reunion Tour line up, along with Blackstreet, Tony Toni Tone, After 7, New Edition, and SWV.
