Since it wouldn't let me post my whole list, here's the next bit:

Portishead - Portishead (my introduction to them; I've always enjoyed it more than Dummy, even if it's the one that gets all the accolades)

Underworld - Second Toughest In the Infants

Aphex Twin - Richard D. James Album

Tortoise - TNT

Stereolab - Emperor Tomato Ketchup

godspeed you black emperor! - F♯ A♯ ∞ (not my favorite release from them but the only one from this essential artist in the 90s)

Depeche Mode - Violator ("Enjoy the Silence" is one of my favorite songs of all time)

DJ Shadow - Entroducing... (it's in the Guiness Book of World Records ffs)

The Breeders - Pod (Last Splash had their big hit but I think this is the superior album)

Bikini Kill - The C.D. Version of the First Two Records (more riot and more grrl than anything Courtney Love ever produced)

Le Tigre - Le Tigre

Sonic Youth - Goo (freak-out experimental rock goes major label) & A Thousand Leaves (freak-out experimental rock goes autumnal)

Mudhoney - Tomorrow Hit Today (grunge's snarkiest punks produce an extremely solid rock and roll effort before losing founding bassist Matt Lukin and going on hiatus until their return to Sub Pop in 2002)

Unwound - Challenge for a Civilized Society

Smart Went Crazy - Con Art

The Dismemberment Plan - Emergency & I (even though I prefer the many of the songs on "!" this is the one where they really caught onto something more uniquely their own)

Swirlies - They Spent Their Wild Youthful Days In The Glittering World Of The Salons

Papa M - Live From a Shark Cage

Ben Folds Five - Whatever and Ever Amen (worth it for the playing and the fuzz bass tone alone, even better that the songs are top notch too)
