Well, it all comes down, w/ Chuck Berry, to in terms of music. Mind blowing if you consider that he was truly the 1st in terms of Rock 'n Roll. His death has caused me to revisit ... & when I think about what it was he did, well, he was beyond enormous. W/o Chuck Berry?, we'd have no R&R great modern music -

90 is a death well earned. You, if you look hard, can see all the greatness that came to pass after. We've lost some amazing artists in my time here on SF, but I think this one may very well top the list.
