Here’s one for the truly dedicated Argerich fans, not, I suggest, for the casual, mildly interested. Available only as a digital download with no booklet or other information, and lasting a grand total of 42 minutes, you can hear the great Argentine pianist in two works from two different Verbier Festivals.

From the 2000 Festival comes a performance of Haydn’s G major Gypsy Trio with her longtime partners Vadim Repin and Mischa Maisky. As far as I can see, this is the first appearance of the Trio in Argerich’s discography (‘I like Haydn’, she once told me, ‘I love his sense of humour’) and is somewhat different to a second live recording she made at the Lugano Festival in 2003 with the Capuçon brothers (Warner). The outer movements are taken at roughly the same tempos, but in Lugano there is a complete rethink about what Poco adagio – cantabile means for the central set of variations. In Verbier it is 4'46", in Lugano an expansive 6'12". And in terms of sound quality, I would settle for the latter – closer, warmer, more detailed. In both cases, Argerich sets a blistering pace for the famous rondo but for me, having grown up with the Cortot-Thibaud-Casals classic, it verges on the frantic. It is pushed that bit too hard and, frankly, lacks the charm of the 1927 recording.

As for the Prokofiev Third Concerto from the 2001 Festival, this, by my reckoning, is the ninth time Argerich has appeared on a commercial recording of the concerto (there are no doubt several more out there). It is a work she has been playing regularly since 1959, a notoriously stamina-sapping 28 minutes in which perhaps the most astonishing thing about the present performance, given when she was 60 years of age, is that it sounds as though it is played by her 18-year-old self. Temirkanov and the Verbier orchestra keep up with her every step of the way, but frankly, if you have the better-engineered DG recording with Abbado and the Berlin Philharmonic, most people won’t need this one.
