Pictures at an Exhibition, in Ravel's orchestration, is one of the most recorded pieces in the repertoire, and I have several versions. Bernstein with New York is a dazzling performance and Reiner's with Chicago is an amazing example of both corporate orchestral virtuosity and RCA "Living Stereo" sound. On a slightly lower step on the podium is Zubin Mehta's and the LA Phil. Spectacularly recorded by Decca in Royce Hall at UCLA.

On the same disc is a youngish Vladimir Ashkenazy playing Mussorgsky's original piano version.
