DJ Jazzy Jeff & the Fresh Prince was an American hip hop duo from West Philadelphia, Pennsylvania. Rapper Will Smith (the Fresh Prince) met disc jockey Jeff Townes (DJ Jazzy Jeff) in the 1980s, when they were both trying to make names for themselves in West Philadelphia's local hip hop scene. They had as a support live member Clarence Holmes (Ready Rock C) – who was not officially credited to the duo. Holmes left the group in 1990 and later sued unsuccessfully for earnings, claiming a breach of oral contract.

The group received the first Grammy Award for Best Rap Performance in 1989 for "Parents Just Don't Understand" (1988), though their most successful single was "Summertime" (1991), which earned the group their second Grammy and peaked at number 4 on the Billboard Hot 100. Will Smith and Jeff Townes are still friends and claim that they never split up, having made songs under Smith's solo performer credit. DJ Jazzy Jeff & the Fresh Prince have sold over 5.5 million albums in the US.
