A passionate recommendation:
20 Feet From Stardom is a current documentary about backup singers. I found this film moving, inspiring and insightful, both for the music story, and as a metaphor for many life aspirations. (Goosebumps, teary eyes, don’t-I-know-it laughter.) I’ve seen it twice and would see it again. I urge you with enthusiasm – if it comes to your area, go! Here’s a list of cities where it’s playing.
