I always find it interesting to read about how people's musical tastes and interests developed, and invariably expanded as they got older.
I have two older brothers who greatly influenced my musical tastes. The oldest one was into stuff like Yes, Genesis, Curved Air and Uriah Heep. These kind of bands were my first love; the first album I really got completely "into" was Uriah Heep's "Demons and Wizards." I was ten. I still enjoy them. Our "middle" brother was more into stuff like The Police, Bruce Wooley, Alex Harvey and Queen many of whom also stayed with me. As a family we used to listen to stuff like The Carpenters and John Denver at home, and much of that stuck too.
At Uni I was lucky enough to be good friends with a guy who had very similar, but broader musical tastes to me, who introduced me to Rainbow, Magnum, Steve Hillage and many, many other similar bands. I was also making my own discoveries like Eloy, Black Sabbath, Jethro Tull, Marillion, Wishbone Ash, Vangelis, Twelfth Night...
A second good friend had a completely different, but very eclectic and diverse tastes from Soft Cell (who I never really go) to Philip Glass, Tomita, Eurythmics, Psychic TV and countless others. It was him who introduced me to Ultravox in the mid '80s. "Rage in Eden" remains my favourite of theirs and I still play it.
I've also been influenced a lot by my daughter who's a classically trained concert pianist. Through her I learnt to appreciate Shostakovich, Gershwin, Mussorgsky, Mahler and numerous other classical composers.
So now I will happily listen to just about anything. I like to think that I'm completely genre agnostic. I trust my ears and brain; if I like it, I like it and that's all that matters.
