Talking about my roots, until I was 12 (1976), used to listen Classical Music (specially Modern Russian), radio crap (top 40) and some classic rock stuff like Deep Purple, BTO, Led Zeppelin.
In that year a new family moved to my block, they had a kid about my age who listened the same stuff as me and a very beutiful 17 years daughter who listened some strange music. Once I tried to impress her with Uriah Heep, and she gave me a cassette with Yessongs. Of course told her I liked the music (But really liked her

), so I started to listen some of her music, as King Crimson, Focus, etc just to be near her, she even sold me in 2 bucks a brand new LP "The Six Wives of Henry the VIII" because her mother bought two copies and nobody wanted to buy that album.
In the same year I went to a concert by a cover band that played Genesis (I think I told the story on other thread), and then it was too late, I felt in love with prog'. So my Prog' roots are Uriah Heep, Yes, Wakeman and Genesis.
By the way, I never had a chance with the girl (she was too old

) but she gave me a gift for the rest of my life, progressive music.
