I don't know how JB is doing on his Beethoven symphony cycle, but I decided to move ahead to Symphony no. 3 aka Eroica.

On CD from the Barenboim/Staatskapelle Berlin box.
The Eroica is unquestionably one of the most important works in the symphonic tradition, and one of the most famous. But it is not one of my favorites, not by a long shot. At the time it was written it was revolutionary, never before had a work of instrumental music encompassed such a wide range of emotional (and technical) content. It changed the course of western art music, and made the symphony the vehicle of choice for a composers most elaborate, if not profound, musical thought.
But for us today, who know Brahms and Wagner, to say nothing of Mahler and Stravinsky it doesn't seem like that big a deal. I compare it to those of us, of a certain age, who were blown away when we saw the original Star Wars movie (esp. if you saw it in a high end theater). But looking back on it almost 50 (!?!?!) years later that opening scene doesn't seem very special anymore (YMMV) because time and progress has moved on.
So, while I certainly appreciate the accomplishment that is Beethoven's 3rd, for me it is about 10 minutes too long. YMMV.
