Elizabeth Clark Phair is an American rock singer-songwriter and musician. Born in New Haven, Connecticut, Phair was raised primarily in the Chicago area. After graduating from Oberlin College in 1990, she attempted to start a musical career in San Francisco, California, but returned to her home in Chicago, where she began self-releasing audio cassettes under the name Girly-Sound. The tapes led to a recording contract with the independent record label Matador Records.

Girly-Sound is the name under which singer-songwriter Liz Phair recorded three self-produced cassettes in 1991. The cassettes were later made available as bootlegs, some songs saw official releases, and the tapes were released in their entirety in 2018. Girly-Sound is also the name used to refer to the demos or bootlegs collectively. The recordings have been called "legendary" by Spin Magazine and by AllMusic "one of the most popular and sought-after alternative rock bootlegs of all time".
