I've just spent a happy hour or so browsing that thread and the Jazz Beat thread.
My experience of SHB is that its jazz threads are just endless repeats of people wowsering of whatever new double/ultra deluxe hereditary audiophilac version of Kind of Blue has been released in the last week. But those two are genuinely good threads. Lots of interesting records I had not been aware of being flagged, with a nice mix of ancient and modern.
