I was listening a lot to them when I was in high school too. I missed them at that time when they were touring with Sebadoh: one of the greatest regrets of my life! Recently I started re-listening to their albums, and they're still as great as they were in my memory. This was a great great band. It's realy sad they didn't have the success they deserved. And I agree: Mac's voice tugs you at the heartstrings when you get into it.
Become aware my man! It's terrific. It's all Mac's music and Bob's vocals. It's called "Go Back Snowball - Calling Zero". It was released on Bob's own Fading Captain series thing. Might be tough to find. I think you might be able to order it from Luna Music. It's 13.99. http://robertpollard.net/luna.html
and you are ill prepared to fight living in a world of soft and white in air conditioned battle zones I pity you!
