Sometimes I'm sure it's simply a matter of good manners, and the people who were around, say, Son House, who were not criticizing pointlessly his deteriorated playing or rambling monologues, perhaps were partly just employing common sense and showing respect**. On the recordings, if the applause and respectful laughter sometimes sounds a little patronising today, it’s easy to understand in view of the conditions these people were often ‘discovered’ in. Then getting to the actual truth involves more than leaping in the other direction, as happened with (for obvious example) the Steve Calt books where everyone involved is thrown in the mud. With Bunk Johnson, long before hearing him I’d read that he wasn’t really worth hearing - similarly with later Billie Holiday, the people who liked her deteriorated voice were ‘ghoulish’ and an appreciation of any ‘accidental’ qualities were pandering to a myth of the tortured artist or something
**this sounds like I'm saying his rediscovery stuff is poor - but I didn't intend it, I like it
