I have an uncle who is 10 years older than I. So growing up I was exposed to what he was listening to at the time. A lot of Beatles, Stones, Frampton, Doobie Brothers, Grand Funk, etc. I also had a friend who had older brothers with a massive album collection. We spent years doing deep dives into the entire catalogues of bands like Pink Floyd, Yes, Hot Tuna, Frank Zappa and bands we never heard of like Nectar, etc.
