I like it best when it's just her and the piano, but some of those concertos are worth her take on it too, like Schumann's Am or Prokofiev's No 3 (the one she learned in her sleep!).
All this made me long for a piano... even though I could never play like her, there is something about playing it that makes everything right for me, somehow. To console myself I resolved I would go and see Hélène Grimaud play with the Symphony when she's here in January. She's supposed to play Schumann's concerto, which she does beautifully too. And maybe I will want this for Christmas.
For now here's a little video of Martha Argerich in her home, when she lived with the Swiss conductor Charles Dutoit, her husband at the time.
And finally, if you can listen past the very crappy sound, another 1965 Chopin competition piece, Scherzo no. 3. I really like this one:
