If you wrote 106 books over your career, most of them would be forgotten, even suck. And if you wrote 106 symphonies in your career, most of them, too, would be forgotten. Not so with Franz Joseph Haydn’s Symphony No. 104 (“London”), a work that proves that much, much practice makes perfect. After a brooding start, it moves straight into classical-era terrain with a roiling, string-heavy series of movements that make you ask yourself, Hey, isn’t this Mozart? No, but the other two works on the bill are: Mozart’s Symphony No. 35 (“Haffner”) and Piano Concerto No. 20. The latter is just like any Mozart piano concerto in the 20s—light, brilliant, glorious, and performed live not nearly frequently enough. According to the program, Philippe Entremont will serve as “conductor & piano” for the Vienna Chamber Orchestra. Perhaps the Austrians are doing more with less too!
