60's u.s. soul documentary

saw a decent documentary about 60's soul and funk record companies like motown or stax. it basically described the different scenes in cities like philadelphia, chicago and memphis. it was great that the artists were presented just the way they were and could talk freely about whatever came to their mind. but the musical parts were way to short and the artist's names were not mentioned. as i am not too familiar with the scene, i'm gonna have a hard time now searching for the songs i liked.
