Wendy Clark (born c. 1962), better known by her stage name Lady B, is an American female rapper and radio DJ from Philadelphia, Pennsylvania. She is one of the earliest female rappers in hip hop, and one of the first hip hop artists to record a single, "To the Beat, Y'all", in 1979. She began her career with radio station WHAT in 1979, and recorded her first single later that year, "To the Beat Y'all". The song, the title of which became a stock rap phrase, was first released by TEC, a local Philadelphia-based record label, and released again in 1980 by Sylvia Robinson's rap label, Sugar Hill Records.
