Oh yeah, no question. I just don't think 60 and 70 years later a lot of those JATP and jam session recordings make for great listening. Some are fun and novel. None of 'em are bad or anything. But I think they're mostly kind of neither fish nor fowl recordings. They don't really have the freewheeling, unself-conscious, free invention of a real informal jam session at its best, and they don't have the kind real communicative give and take of a working band performance or even jam. They're just kind of strings of solos. For me, as a listening experience, I don't find they've aged that well, though some are more exciting than others. They're more like novelty time capsules than great performances that reward repeated listening.
