My mom got me into Red Hot Chili Peppers, and my dad helped me get into The Beatles.
Those are the most notable that I still listen to.
My parents also introduced me to such bands as Aerosmith, Kiss, The Rolling Stones, etc.
Most of my earlier metal tastes (Metallica, Black Sabbath, Ozzy, Iron Maiden, etc.) came from my uncle.
So I guess my parents gave me the rock background which helped me get interested in metal thanks to my uncle which in turn enabled me to get into other genres eventually leading to where I am today, in part thanks to Quadrochosis.
