December 16, 1770:  birthdate of Ludwig van Beethoven.

That was 250 years ago, and this year, the exact anniversary falls on a Wednesday. Lone Tree Arts Center will honor the occasion with a Beethoven-themed online Arts in the Afternoon program. We’ll welcome the Ivy Street Ensemble – violinist Erik Peterson, violist Phillip Stevens, and special guest, pianist William David – with concert host Betsy Schwarm. You’ll have to provide your own birthday cake, but we’ll have the music, streaming it live to your computer. Please join our celebration of the 250th anniversary of Beethoven’s birth!  Buy Tickets
