I also thought it would sell slowly. I held off purchase for a long time for that reason, and because the discography didn't overly impress. Finally bought it last October when Mosaic had a free shipping offer (iirc). The first couple of hearings, I wasn't knocked out, but I did some intensive listening recently and have come to really enjoy the set. Brackeen and Sanders sessions were the most pleasant surprises. Recorded sound of the piano on discs 1-2 is bad, but I got over it.
