This is a very important recording, as it is the first time the original piano quartet version of the Eroica Symphony has been recorded. (it should not be confused with the arrangement by Ferdinand Ries published 50 years later). This anonymous arrangement was made at Beethoven's insistence (though he had requested a string quintet) and published in 1807, three years after the orchestral premiere. The writing is far superior to that of Ries in the later version, and this work stands as a fine and magisterial piano quartet in it's own right.
