This is a great bargain for a Tchaikovsky fan or would-be fan looking to get the piano concertos. Pletnev is an incredible pianist. Sure, there are others who do parts of these concertos better, but then there are parts that he does better than all the rest, too. Don't limit yourself to one recording of the first piano concerto, but this one makes a fine start.
The second is much harder to find, so I'm really happy they've made it accessible in this set, and for such a great price. Again it's very well executed. And for those who haven't heard it yet, you've got a treat coming! You may or may not like it as well as the first (I do), but in any case rest assured that it is as full of beautiful Tchaikovsky melodies.
The third is uncompleted -- quite nice, but I don't listen to it much, and so can't comment here.
What really makes this a special set, though, is the inclusion of the Concert Fantasy. I had never heard it before, and for awhile ignored it, assuming it was just there as filler. It's not: it's a stunningly beautiful piece that you should be sure to listen to. I hadn't even heard OF it before I got this set, and whether that was my fault or that of the Powers that Be, I thank the producers for introducing it to me here. It will remain one of my favorites.
