While I'm usually correct, I try to not let it go to my head like a 20something who claims to know everything.
Still, thanks for the reference to the movie. It's well rated and looks interesting. I travel quite a bit and, frankly, am too old to do the bar scene, so a good movie reference is always appreciated no matter if it's offered maliciously. Good documentaries are high on my list of watching material and this movie fits the criteria.
Satan & Adam (2018) - IMDb
SATAN & ADAM chronicles the unlikely pairing of legendary one-man-band Sterling "Mr. Satan" Magee and harmonica master Adam Gussow. Shot over 20 years, the film showcases one of the greatest blues duos you probably never got a chance to see. Magee and Gussow came together on the streets of Harlem in the 1980s, a time when race relations in New York City were at an all-time low. From completely different worlds, these two musicians forged a lifelong relationship that showcases the unifying power of music.
