My teens were an awfully long time ago, so without rummaging at the back of the stair cupboard for my old vinyls, I had to look them up to remember the titles. If my teens count up until I was 20, the ones that I can remember that I liked:
Wishbone Ash; Pilgrimage (1971), Argus (1972), There's the Rub (1974).
Allman Brothers Band; self-titled (1969)
Led Zep; Untitled (1971)
David Bowie; The Rise and fall of Ziggy Stardust (1972)
Jonathan Kelly; Twice a round the Houses (1972)
Fleetwood Mac; The Vintage Years (1975), Rumours (1977)
Outlaws; Bring it back Alive (1978)
Bob Seger; Stranger in Town (1978)
I also remember some Jethro Tull thing and Lynyrd Skynyrd and Deep Purple albums; neither of which I can remember the titles of.
The dates are when they were released, not when I bought them. I don't think I actually bought any until I got a Saturday job when I was about 17 and then I started work at 18, but all of those I would have listened to with friends or went to music shops for a listen. Anyway, I would imagine that the vinyls are close to worn out now.
