At 17 I was really big on:
Urge Overkill
Neil Young
Bob Dylan
CCR
Uncle Tupelo
Tom Waits
Ry Cooder
NoMeansNo
Fugazi
Palace (just)
- a bunch of great local bands nobody outside Edmonton's heard of (
the smalls,
Imagineers, Naked and the Dead/Old Reliable, etc)
But I was also obsessed with a bunch of pre-WWII blues stuff (I distinctly remember reading a public library hardcopy of Alan Lomax's
The Land Where Blues Began. I think this was the year I first heard
Charlie Patton via a guitar teacher who introduced me to:
John Fahey
and
Leo Kottke)
I think grade 12 was also the first year I really started listening to jazz. I bought the 4-disc Verve boxset, and then worked my through a lot of bebop and hard-bop.
I also dipped my ears into 20th Century classical and "new music" about 12th grade.
It wasn't 'till I was about 20 that I found my way fully into "postrock" territory - fell in love with the s/t Tortoise album, Don Cab, Slint, Shellac, etc.
It wasn't until last year that I heard Bedhead thanks to this very online forum (easily one of my favourite bands of all time, I suspect).
