They were both great. Spiderland is so great it makes Tweez look bad in comparison, but if you actually listen to it it's still a great album. It's like a funky version of Big Black. Most of the criticisms I've heard of it are pretty unfounded and show that the person should go back and listen to it again.

Tweez has some good SONGS on it, but they just sound bad. Take Rhoda for instance, it's an amazing song on the Slint EP, but on Tweez it just sounds flat and boring.
The guitars sound amazingly shoddy too.
Darlene is the only song I really like listening to on Tweez.

BUMP

Steve's amazing. Respect to no damn end. Everything I've heard with his name on I love.

The guy is a cockface. Most of his music was good though.

I've been listening to big black and shellac a lot recently. i particularly love shellac, they just do it for me on so many levels. production wise i havent given him much attention.
