Were The Grateful Dead a jazz band?

[chouchou]

18. No big deal. But, when I listened to the Dead, I recognized licks and chord spacings..

...that were a little overdone. (OK a lot overdone) They played some nice riffs but what they played
were them standing on shoulders of jazz cats that had been played hundreds of times.
I understand I'm being critical...but having the curse of Perfect-Pitch is good and bad at the same time.
The truly hot-licks come from a deep place and make one says "Jesus Christ...Where did THAT come from?
"Never heard that run before" Cheers

You probably know this so excuse my ego.... When someone has Perfect Pitch, they don't need to look at the sheet music.
If you hear a new song..you can write the whole chord structure, all the notes, what key it's in and more...in about 2 minutes.
On the other hand ..When you hear a shitty band, you want to leave NOW!! No..The Dead were no shitty at all.
