Jon Batiste Hears Green Day For The First Time

@danielpunkass Watching the video, Jon can definitely "see" music that I can't.

As a non-musically inclined person, I am constantly asking myself what is he looking at.

@queuebit He's a remarkable genius.
@danielpunkass @queuebit please check out his new “Beethoven Blues" album if you haven't. It's really something special.
@queuebit @danielpunkass he has perfect pitch so he can identify the notes being sung / played much faster than most of us. Then he knows music theory well enough that he knows the chord progressions. After that he can assemble his massive improv skills and transform that to music.
