I’ve been listening to several collections of harpists living and dead, and some of the recordings certainly do deserve to enter the “worst” category.
Has anyone heard a popular commercial recording during which it sounds as though the music stand has fallen over the harp with a resounding, metallic crash. Subsequently there are what sound like several attempts to right the tipped stand unsuccesfully. All very audible. On the same recording, there is a pedal harp with a very loud, metallic tone, although all of the notes are correct (no percussion from dropping objects). I wish I could remember the piece but it was something quite familiar.
Can’t think why the “dropping” piece wouldn’t have been re-done though. The jacket of the CD says nothing about it being a concert performance.
