I saw the Motown movie, it was pretty good, kind of an amateur production but a great story to tell. I never knew the history behind all those talented studio musicians and how they got screwed when Motown moved to LA.
They soundtrack of the movie is excellent, I play it all the time when I’m working in my shop.
There’s a good series of videos about The Band, the Music from Big Pink boys, available on youtube. Gives you some great history of that group and all of the people they worked with. Which seems to have been virtually everyone.
I think this is the link to the first video; this version includes Japanese subtitles for your added viewing pleasure:
