That's Miles Davis! lol
He didn't bite his tongue!
Sometimes when he was into his feelings he'd turn his back on the audience and continue playing until...lol
He didn't give a shit!

He used to criticize Rock N Roll guitarists as being overrated and just noisy, and that included Jimi Hendrix..
Then he confronted Jim Hendrix one time in New York city and ask him to play a Jazz standard on an acoustic guitar. Hendrix didn't only know the tune, he played it easily!
Miles was stunned!
So stunned that he wanted to have a recording session with Jimi...

The mistake most folks make about Jimi Hendrix is that he was a great guitarist but mostly into reverb, feedback, and Rock showmanship..
But put him on an acoustic guitar and he'd pour out fluent notes and sophisticated chords. I swear!

Worth noting that Miles was a very dark skin guy, and you know the extra shit he probably went through both inside & out!

btw, did I mention that Miles then suspected his girlfriend of sleeping with Hendrix. Oh lawwwd
