Yeah, I was a pretty big fan, and as annoying as it is to say this, their earlier stuff is just great compared to anything that came later. The tipping point for me was probably Happy Songs for Happy People, which had some of my favorite tracks of theirs (Moses? I Amn't and Hunted By A Freak, of course) but anything after that wasn't enough for me to really keep up with whatever they were doing. Probably just my own tastes changing or something.
Sine Wave though, now that is a very special, very powerful song. I occasionally go back to every year or so, along with 2 Rights Make 1 Wrong and You Don't Know Jesus. All from Rock Action, coincidentally. These are songs I like to play loudly with whatever kind of stereo I may have set up that I'm testing out.
