The Philadelphia Clef Club dates back to the golden age of Philly jazz. In 1966, it was formally organized as the social arm of Union Local 274, the black musicians union, whose members included Dizzy Gillespie, John Coltrane, Benny Golson, Bill Doggett, the Heath Brothers, Jimmy Smith and Nina Simone.

Over the years, the Clef Club has had five locations, including Broad and Carpenter Streets, and 13th Street and Washington Avenue. The Philadelphia Clef Club of Jazz and Performing Arts moved into its current location on the Avenue of the Arts in 1995. This construction fence told part of the story of the house that jazz built.
