a few that I own and enjoy:
Southpacific - CONSTANCE on Turnbuckle Records, 2000.
Great if you're into the late Slowdive sound.. on many tracks you can almost imagine that if Slowdive wouldn't have morphed into Mojave 3, they might have sounded something like this.
The Autumns - ANGEL POOL on 404 Music Group, 1997
Definately worth checking out if you're into the late 80's Cocteau Twins sound.. big washing swooshy guitars and cavernous echoing drums. But not too heavy, very floaty.. also, the songs are more stretched out and longer than many more pop-oriented tunes from the early 90's gazer era.
Do you have any Bailter Space? They've not new by any means, but if you haven't heard them, check out their album ROBOT WORLD. One of the best shoegazer albums of the early 90's.. They can rock hard but can also lay down really sweet beds of bliss-out distortion. Probably most similar to Catherine Wheel, if you've heard them.
One more I might suggest, a little more well-known is Yo La Tengo's I CAN HEAR THE HEART BEATING AS ONE. This album is all over the place, lots of styles, many accoustic moments but also lots of fuzzy bliss as well. Definately belongs in your collection if you're a shoegazer fan.
