(The lack of needing to pay "star performer" fees probably helps here!)
I have my own doubts about that (see earlier). 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. Then again, people said we were lucky to have ersatz chicory 'coffee' to drink during post-WW2 rationing, too....
