Lately, I have discovered Liszt's piano transcriptions of Beethoven's 9 symphonies. Very great stuff! I'm used to hearing the symphonies as they were originally composed (who isn't?), but hearing them played on a piano is much like hearing the something different, while, at the same time, recognizing all of the various parts of the original orchestration It has an interesting effect, almost like watching a film in black and white. You know all of the various parts of the symphony and how they sound, but your mind is more active in making the connection between the sound of the piano and how you are used to hearing it. Just like how your mind works visually while watching a film in black and white.
There are other re-orchestrations I have heard (i.e. Mahler's re-orchestration of the 9th), among others. But, the effect just isn't there when an orchestra is playing a different version of an originally orchestral piece--there's just not enough difference in sound. The more minute sound of a chamber ensemble or piano seems much more effective.
I mentioned the Liszt piano transcriptions, are there any others anyone can recommend? Perhaps either solo piano or chamber?
