I am not sure music is well-served when recorded in a slapdash fashion by a no-name orchestra from a provincial town in Bulgaria. Especially when you can hear distant aircraft flying overhead during the pianissimo moments. The music is placed at an automatic disadvantage. Some would say 'we're lucky to have any kind of recording', of course.
For recordings of obscure material where the playing is poor, you unfortunately have these type of recordings in context. Everyone probably has a tolerance level for this (I personally have a tough time digesting the lo-fidelity early recordings, at least for classical music, for instance) so I can understand a poor performance being an instant turn-off for some.
Of course, there are many very-good-to-excellent performers / orchestras / conductors who are not "stars". I think the better independent labels releasing lesser known material mainly use these type. The better independent labels also don't really skimp on the engineering and production so airplane noise is not usually a problem, either. :)
