My favourite musical discovery of 2020 is actually my discovery of someone else's 2020 discovery (albeit 43 years after the music was made).
Namely, watching accomplished online guitar teacher Michael Palmisano's joyous reaction as he listens for the first time to Jerry Garcia's most zenithal of zenithal moments (and there were many), in his newfound discovery of the Dead. That's EXACTLY how it gets me too, every time I listen to it. Thankfully I've known about it for many years.
Nice too to have some analysis of what was going on, and what makes it so good, but in his excitement he overlooked the exquisite pinched harmonic where Jerry bursts through into a new universe (23' 56").....
Fortunately for Dead fans, he's gradually working his way through the entire 8 May 1977 concert at Cornell. Here he is, utterly engrossed and virtually lost for words by Jerry's outstandingly poignant playing and singing, and the whole band's performance, on the beautiful
Morning Dew.
