Guy was a popular 1980s and 1990s hip-hop, funk, 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 1990s 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 1988. Gatling left after the first album was done and was quickly replaced by Aaron's younger brother Damian.
