... and from an entirely different part of my brain ... I can only reiterate yesterday's enthusiasm for the Kurtag CD.
This is some of the most exquisite & powerful music I have heard. Full stop. The tiny scale & fragmentary nature of the 'pieces' (exactly the word in this case) only serve to intensify the pure experience of sound. A comparison with Beckett's late prose is absolutely justified if a bit obvious.
Incidentally, there is also film of Kurtag & his wife playing the piano on YouTube. (You'll find it easily). While the Argerich Barenboim performances were impressive, these are perhaps even more so given the respective ages.
If me & the missus can be playing duets in 40 years time - well, you're as young as you finger.
