2. James Brown
Adding to all his monikers - The Godfather of Soul; The Hardest Working Man in Show Business; Soul Brother No. 1 - James Brown is now known as a serious style icon of the 1970s. His initial commercial breakthrough came in the previous decade, but it was in the '70s that he earned his nickname titles and his musical dominance and incredible style took off.
JB is undoubtedly one of the most entertaining frontmen of all time, and his wardrobe was on par with his unique dancing and off-stage fast lifestyle. As a founding father of funk, it's pretty obvious that his wardrobe had to be at a level beyond what anyone else was doing at the time, inspiring copycats and imitators for years to come.
