I'd like to think this attempt to capture the profound depth of the deceptively simple "Variations" on harp is a gallant effort that failed, rather than a calculated marketing move to bring attention to a less popular instrument (but what's wrong with THAT, really?) Anyway, at the end of the day it came down to the same thing: a performance that one is not likely to revisit.
But should we give up on harp for "Goldberg"? Perhaps. But Finch here may not have done the instrument a lot of services. For example, only part of the failure to arouse the same anticipation and subdued drama as in a beautiful piano deliverance, which makes the 1st movement so exciting to hear every time as if afresh and, in my case, suggests picturing one' self tip-toeing down the marble stairs to a door that opens to a whole different universe, is due to the limitation of harp. Perhaps Finch's "timing" is just not very good.
