One of the most successful funk bands of the 70s, the Ohio Players had a string of crossover hits like "Fire" and "Love Rollercoster." They also had quite a reputation for extreme partying. The stories are unsung.
The Bar-Kays backed up Otis Redding and endured shifts in Black music for over 40 years. Other bands may have greater hits, but not greater longevity than this unsung group.
