While the Isley Brother's made it famous, Curtis Mayfield actually wrote this song back when he was a part of the 1960s soul group: The Impressions. Mayfield and the Impressions had a pretty big impact on the Isley Brothers sound and soul music as a whole. After a long career with The Impressions, which included tracks like "It's all right", "Gypsy Woman" and "People Get Ready", Curtis Mayfield went on to pursue an impressive career of his own. With a sound that is unmistakably his own, Mayfield created one of the best film soundtracks of all-time for the movie Superfly. With tracks like "Superfly", "Move On Up" and "Pusherman" being the most prestigious on the album, Mayfield set himself apart. There was no holding back, to say the least.
I suggest that you all go out and get a copy of the Superfly soundtrack as soon as possible. Until then, enjoy the Isley Brother's rendition of one of Mayfield's legendary hits: "Who's That Lady."
