Tim Page listens to a live piano “recreation” of a Glenn Gould performance. Is it good as Gould? “It shows that such ventures are increasingly possible — on the piano, at least (for various technical reasons, it is impossible to imagine this working for violin, cello or the human voice). Moreover, there can be no doubt that Gould, whose fascination with new technology was unlimited, would have been thrilled by this development: The quirky and reclusive genius would have liked nothing better than to give ‘live’ concerts without having to be there.”
