Yeah, it's crazy how rare their albums are. I only have 3 of their albums on CD myself: Collusion, Digilogue, and What Is Not True. I also have their Mort Aux Vaches sessions that I downloaded from Amazon while it was up briefly. Legendary group for sure and there's nothing else quite like them.
Hafler Trio is bad about that too, but Andrew McKenzie is supposed to be really curmudgeony nowadays about digital music and doesn't want his music being circulated around anymore IIRC.
