If a customer purchased five albums from this collection separately - after this compilation was published in 2013 - he would have paid more than three times the price of this. Yes, it's THE bargain.
As for Martha Argerich, one of the most unique and revered pianists of our era, the five albums (recorded in 1979, 1997, 1998 and 2002/2003) offer a comprehensive cross-section of her artistry. One slight exception is a lack of chamber music performances, just the rare Triple concerto (late Beethoven) is included here - but with Mischa Maisky on cello and Renaud Capucon on violin there is also the entire Swiss-Italian orchestra.
Therefore, concertos abound here - including her perennial favorites. Both Chopins, Prokofiev No.3 and Schumann were recorded by EMI after some three decades since the first recordings for Deutsche Grammophon, all showing her ripe, competent technique.
Prokofiev No. 1 and Bartok No. 3 she recorded for the first time in the late 1990's, also captured here.
As for the solo performances from Amsterdam (1979), these show some kind of extra energy the Argentinian pianists felt during the live performances. This sometimes has an impact on the quality of play, as, for example, Precipitato of Prokofiev's 7th Sonata is rather rushed - maybe because of too much adrenaline. However, Schumann and Ravel by Argerich are hard to beat anywhere. She's born to play both. Even though, especially at Ravel, she's speeding.
All five albums capture Martha Argerich in all her glory and show an interesting contrast between a still wild soloist in the late 1970's and the mature team player two decades later.
