Listening a lot to Lynyrd Skynyrd lately, as I discovered outstanding remastered/cleaned performances on youtube
These were the kind of bands I liked gigging with most (RnR cover bands back in the '90s)
But if I were to put my finger on one of the first albums that made me realize Bass (I was 14 at the time): Mark King’s Level 42, Lessons In Love was aired over and over a summer I spent on UK to learn English back in mid 80’s.
I guess the fact of the lead singer being the bass player, and specially King’s slap/machinegun style, a sound that wasn’t that widely known back then (let alone in Pop music!) made it stand out even more for me.
