Phill Niblock, himself a notable composer in his own right, made this lovely, minimalist filmed portrait of Sun Ra and his Solar Arkestra in 1968. Shooting them on a rooftop in high contrast black and white and focusing in on fingers and mouths, this is as good an excuse as any to take 17 minutes out of your day to enter the waking dream world of Le Sony’r Ra.
 

 
Bonus clip: Another late 60’s film portrait by Phill Niblock, this time of the late great percussionist/composer Max Neuhaus:
