I lived with my Grandmother till I was 4, my first exposure to music was the records that my Mother & my Uncle had left behind when they both went to college. I fondly remember those 45's...Rolling Stones, Steppenwolf, The Beatles, The Guess Who, Badfinger, etc...plus albums like Bill Cosby's Himself, Pet Sounds, Beggar's Banquet...
Later when I went to live with my Mother I started listening to CSN&Y, Jim Croce, Seals & Crofts, James Taylor, Judy Collins, Janis Joplin, The Doobie Brothers, etc.
When I was 6 years old (1976) I discovered Kiss...that was when our paths diverged. I think the last album we both loved (at that time) was Heart's Dreamboat Annie. Kiss was followed by Boston, Alice Cooper, Ted Nugent, AC/DC, etc.
She got tired of listening to that stuff so she decided to turn me on to "higher quality" rock: Jimi Hendrix, Pink Floyd, Queen, Yes and others.
I diverged yet again when I discovered Iron Maiden & Judas Priest (1981 by this point). Again she questioned my taste and again she countered with bands that she enjoyed: Led Zeppelin, Deep Purple & Black Sabbath. I'll always be grateful for that..I still listen to them today.
(I've never quite figured out how I missed Zeppelin during the 70's, I listened to the radio all the time but I never owned a copy of Zep 4 until 1982)
It's funny that she has never gotten used to my love for jazz. She appreciates the talent involved but it just doesn't "hit" her. It's okay though, we can still hang out and crank In Rock to 11.
