You summed up my thoughts about this album entirely. It is such a shame that the recording does not shine because the musical performance is excellent. I went to the tour concert at the Locarno in Birmingham, a fantastic gig.
EDIT - This album was originally released on vinyl, and I doubt it was recorded in digital. Digital pop recordings tended to lag behind classical by a few years although there are a few exceptions. When music companies were busy issuing CDs of recent recordings to build up a catalogue, my view is that many did not receive optimum care and attention, the labels’ main concern was to build a big CD catalogue.
