Which band or record changed your life?

Ok there's been a lot of these types of threads lately but I was thinking about this on my way to work this morning.

Me? I'd have to say Huker Du's Zen Arcade totally blew my mind the most. I'd been into punk and underground stuff for a little while, but when I heard that record I knew I wasn't alone in the universe. Almost 20 years later I still love it just the same as when I was 14 years old.
none
Joy Division- "Closer"

Changed how I listened to music
Radiohead - OK Computer
don't laugh: DM "Music for the Masses", '87 - perfect timing to release all that teenage angst; misery loves company.
Shaggs-Philosophy of the World
u2-joshua tree

it moved me away from more popular music and classic rock to what was then considered alternative and rock.
Madonna - You Can Dance
The Pixies 'Doolittle'

The The 'Infected'

both albums had this instantaneous, holy shit, what was that I just listened to quality
rem- out of time, followed closely by pavement's "crooked rain crooked rain"

let's just say, that at the time out of time came out, it was exactly what i needed to hear (except for radio song and shiny happy people), and it put me on the musical road that i still am travelling. not to mention that "country feedback" is a fantastic song.
public enemy–it takes a nation of millions to hold us back
Definitely the first Vanilla Fudge album, which provoked the inspiration that spending several years stoned senseless would be the optimum use of my time. Definitely life-changing.

Um, you weren't specifying "changed your life for the better," were you?
Dead Kennedys "Fresh Fruit for Rotting Vegetables"
Not that it changed my life, but The Housemartins' "London 0 Hull 4" was important in the sense that after that album I started to go more often to record stores and look for new and different (meaning not the bands you had all day long in the radio) bands.
actually I would have to say Beastie Boys - License to Ill, my dad brought it back from the US for my brother (I got Whitesnake :( ), I must have played Brass Monkey 100 times in the next few days, I hate the song now, but that album was so different to other music I heard then
Pink - She helped me find my inner confidence when I needed it most!!
The Housemartins' "London 0 Hull 4"
first LP I ever bought - still listen to it
Honorable mentions for me:

U2 - Under a Blood Red Sky
Violent Femmes - self titled
4 old 7"'s on a 12" - Dischord sampler w/ SOA, GI's, Youth Brigade & Teen Idles
Velvet Underground and Nico
When I was a kid, it was

I had listened to nothing but radio pop before hearing it.

As a teenager, as boring as it is, it had to be

It got me into listening to music again, and pretty much lead me on the path (musically speaking) that I'm on today. Trite, yes, but you try finding new music growing up in Sykesville, MD with no older sibling.
