Kanda makes ya wonder what buddy holly and ritchie valens would have sounded like in the 1970's and 80's

RJD was amazing live, got to see him with Heaven & Hell a few years back 3rd row right in front of Iommi & Judas Priest closed the show. I'll add Motorhead / Theory Of A Deadman / Rob Zombie were before them.

Holy feces! I had no idea!!

Fortunate to see Dio with Sabbath after Heaven and Hell. And before that, with Rainbow. I'm going to have to look at the old doo-wap stuff again for more inspiration...
