Here's a link to their annual event and their description:

The Friends of the Morrill Homestead invite everyone to attend a free Open House. Come tour the house, stroll the trails and visit the gardens in bloom. Refreshments and dessert are “on the house,” making this event a real summer confection! To top it off, the Friends are hosting a live performance at 3:00pm by the renowned musician Spencer Lewis, that’s open to all.

This concert is a duo w/ mandolin /guitar accompaniment.
