Singer/songwriter Katie Hammond began Bear Grass in 2012 as a solo-project, creating quirky songs with lyrics drawing from her childhood memories. Over the next two years she was joined by Ian White, August Sagehorn, and Tommy Krebs who provide a blend of folk, rock, and trip-hop to compliment her warm yet sorrowful vocals. The Troy-based band last played at Upbeat in 2015.

For its 18th season, the Upbeat on the Roof summer series highlights regional musical talent every Thursday, July 5 through August 30 from 7:00 - 8:00 pm.

Performances are free and open to the public. The rooftop is accessible via the museum elevator or outdoor staircases. In the case of inclement weather the series is held inside the museum.
