Traverse earthwork sculptures, enjoy live music, and admire found-object artwork for a musical cause. Opus 40, Harvey Fite's six-and-a-half acre bluestone labyrinth, hosts a benefit for Hungry for Music—a nonprofit that provides free instruments to underprivileged children throughout the United States. The one-of-a-kind sculpture park and museum holds "Musical Visions: Live Music & Art Auction" on Saturday, May 4 from 4 to 7pm. More than 30 local artists, including bricolage artist Polly Law, transformed old musical instruments into paintings, sculptures, and assemblages—which will be sold during a silent auction. Admission to the event is by donation, including worn but functional musical instruments.
