Greatest Music Documentary?

"Beware of Mr. Baker", documentary on drummer Ginger Baker

The Gospel According To Al Green.

Thanks for the tips, now I know what to do in this holydays.... And there is this documentary with Hugh Laurie, following the footsteps of Profesor Longhair, for got the title, saw in netflix about a year ago.... Pretty funny

Thanks for the clips folks.

One problem with music videos is that too often the video people haven't got a clue about music, so just as the lead guitarist starts his solo the camera switches to the drummer. Or similar. Scorcese went to great detail to get "The Last Waltz" right.

Mountain Goat, thanks for the Al Green link. I will watch that. If I set the alarm I wake up to him singing the Willie Nelson song, "Funny How Time Slips Away"
