Fast rapping was hot and "Supersonic" way before Twista! The '80s was the time for the ladies, running hip-hop! All-girl group JJ Fad shot onto the scene with their mega 1988 hit, "Supersonic". The S is for Super and the U is for Unique... You remember the jam! We found the video, so check it out... Do you remember what you were doing the first time you heard this song?
