In 2010, a group of local artists, doctors, and a dentist came together around a simple idea: Bring a band to town in exchange for dental work. Since then, the O+ Festival has hosted hundreds of bands and performers, filling the city with music for one glorious weekend each October.

During festival weekend, you can hear live music at a variety of both traditional and unique venues around town – from breweries and galleries to parking lots and alleyways, and even within the soaring cathedral of the Old Dutch Church. 

While the vast majority of participants are local – in 2022, 68% of all musical acts were from the Hudson Valley –  O+ brings musicians from all over the U.S. (and sometimes, beyond!) to exchange the art of medicine for the medicine of art.
