there are two that stand out for me

1) Ash - 1977 got me into Indie music for the first time, quality album.

2) Eminem - The Marshall MAthers LP - had never listened to any Hip Hop / Rap before this, but i listen to quite a lot now.

exit planet dust was pretty influential for me, can't think of too many others except maybe the bends.

Razzler

Current Eminem not enough to get you out of it then ?

Herman Bloom

What jk said about exit. Never been anything other than an indie kid before then.

Not an album, but hendrix got me into playing the guitar (on a very basic level).

postal postie

the haunteds debut album got me into thrash metal
descanting the insalubrious was another album that got me into the heavier side of music

H.O.V.I

Nas-Illmatic

Weezer-Make believe

Moreclaw

And Justice For All by Metallica got me into metal in general.

Scenes From A Memory by Dream Theater got me into the progressive side of metal / rock.

James Tringham

Otis Redding - Otis Blue. Got me into Atlantic Soul.

On a tangential note, quite a lot of what I listen to I got into because of a book called "1001 Greatest Singles Ever" by Dave Marsh. Sam Cooke, Doo-Wop, Van the Man, '60s garage, Ray Charles, etc. Really recommended if you ever find a second hand copy. It must be nearly 20 years old now.

Motion by The Cinematic Orchestra got me into both Jazz and Electronica.

I will be eternally grateful.

punkskamonkey

Offspring - Americana started me on the whole punk thing.

Less Than Jake - Borders and Boundaries into the ska direction

Then it's difficult to pinpoint other specific bands or albums that got me into other bits.
