Recently picked up 2 Bongripper albums, haven't had a chance to listen to much of them, but I dig what I've heard. They're instrumental so if vocals are a turnoff, they might be of interest to folks.

Re: Ancestors. I've got all their albums, but tend to reach for the last couple more often than the first two. That said, I agree they lay the Floyd stuff on a bit too thick at times these days. Heck, the cover of In Dreams could have been done by Hipgnosis.
