Szymanowski's "Symphonie Concertante" (Symphony no. 4 op. 60 ) - Piotr Anderszewski, Sylvain Cambreling, SWR Sinfonieorchester Baden-Baden und Freiburg, 04 02 2011, Warsaw, Nat'l Philharmonic Concert Hall

This is only part of a concert held on the occasion of the Chopin Year. They just did not broadcast the rest.

So this is just an E.P. treat for Anderszewski fans, showcasing an amazing piece of music.
The piano part itself is not overly complicated, written to suit the performing capacity of the composer.
