Name a few albums which helped determine your musical tastes

Off the top of my head, here’s a few:

CCR - Chronicle
Chuck Berry - Greatest Hits
AC/DC - Back in BlackLed Zeppelin I
G N’ R - Appetite for Destruction
Neil Young - Harvest
Nuggets box set
Metallica - Ride the Lightning
Steve Young - Seven Bridges Road
The Dream Syndicate - Medicine Show

Music that opened my eyes to different directions (in order):
Simon & Garfunkel - Bookends; The Who: Who’s Next; Yes: Close To The Edge; Elvis Costello: Imperial Bedroom; Peter Gabriel 3; Debussy’s Tonal Works- my introduction to classical; REM: Chronic Town - single-handedly saved the world from White Snake; Jane’s Addiction: Ritual de lo Habitual; Beethoven’s 9th - one of those epiphanal moments; Radiohead: OK Computer; The Shins: Oh, Inverted World; Ralph Vaughan Williams - Fantasia on a Theme by Thomas Tallis; Sun Kil Moon: Ghosts of the Great Highway; Sufjan Stevens: Illinois; Gorecki’s 3rd

Now this is an interesting question! I’ll probably have a boring answer, but the question is fascinating.

This is slightly odd for me, because my life has two very distinct parts. I’m going to focus on the things that have shaped me in the second part. Nothing in the first part is worth focusing on, and not much in it was worth listening to (and I don't just mean the music).

• Gillian Welch / Revival
• Greg Brown / Slant 6 Mind
• Townes Van Zandt / Rearview Mirror
• Wilco / Summerteeth
• Jim White / No Such Place

• Mississippi John Hurt / (can’t remember the album name)

• Frank Sinatra & Antonio Carlos Jobim / Francis Albert Sinatra and Antonio Carlos Jobim
• Neil Young / Harvest Moon
• Rufus Wainwright / Poses

There are others, but I imagine this list is already long enough nobody will read it. :)
