"That Lady" is a song by #theIsleyBrothers, made famous in 1973 when it was reworked in a #funkRock style. It was originally performed as "Who's That Lady?" in a classic #RAndB vocal style by the Isley Brothers in 1964, inspired by #theImpressions. In 1973, the core Isley Brothers vocal trio had recently expanded, picking up guitarist #ErnieIsley, bassist #MarvinIsley and keyboardist #ChrisJasper to form their 3 + 3 configuration.
