Beethoven’s only Violin Concerto isn’t just musically risky - he actually finished it as late as he possibly could.
It wasn’t uncommon for Beethoven to be casual with meeting deadlines, but for the Violin Concerto, he finished the work right before the premiere. This meant that the soloist basically had to sight read the work at the very first performance. It’s our Evening Masterwork tonight at 7 on Classical WSMR 89.1 and 103.9.
