With her doe eyes, cascade of hair and sinuous dance moves, Ms. Summer became the queen of disco — the music’s glamorous public face — as well as an idol with a substantial gay following. Her voice, airy and ethereal or brightly assertive, sailed over dance floors and leapt from radios from the mid-’70s well into the ’80s.

Her music was featured in the Broadway production Rock'N Roll! The First 5,000 Years.
