One thing people would be surprised about is that although hard rock and heavy metal are without question 90% of what I listen to and my passion, there are other things I enjoy. My first ever favorite band in my life before KISS was a power-pop band called The Raspberries.
Black Sabbath invented heavy metal, in my opinion.
The power chords in 'Come Sail Away' were super heavy to me as a kid. Metal? No. Hard rock? At times, for sure.
