1993:
That's about as it gets for me. I may have some others lying around somewhere but I can find anything remotely interesting enough that far back other than this.
Edit: Most of my albums are on my external hard drive now-a-days.
I've re-listened to it and I don't even mind them singing in the two tracks. It fits in there fine by me. Skullcap, Microcondian, Araras are my favorite tracks. Overall, it's good quality music.
