This is an interesting one. I do keep a playlist of songs that have had memorable appearances in movies, so there’s plenty to choose from even if one were to exclude musicals. The one I choose isn’t on said playlist, funnily enough, but it would be if I could find it on Spotify.
The scene in question is from Black Snake Moan. It takes place in the later parts of the film. Lazarus (Samuel L. Jackson), a retired blues guitarist, decides to play one more gig at the local bar and takes his new ward Rae (Christina Ricci) along. Rae is a nymphomaniac who’s been trying to overcome her urges, and Lazarus has made just that his mission. So while this scene works just fine as an isolated performance thing with the badass SLJ in full form, it gets added meaning within the context of the story; it’s Rae’s first real “test” since starting her unorthodox treatment. We get to see her out and about, dancing and having fun, and we wonder if she’ll succumb or not.
And it’s such a great-looking scene too. Granted, the first half where Lazarus plays “Alice Mae” isn’t particularly remarkable. It’s when he switches over to the profanity-ladden and vicious “Stack-O-Lee” that business really picks up. Watching the sweaty crowd dance around in slow-motion is a thing of beauty. It’s a hot scene in all senses of the word.
