Chamber ensemble The Mana Saxophone Quartet will perform "Forest Music" at 5 p.m. Thursday, June 5, at Adkins Arboretum, 12610 Eveland Road near Tuckahoe State Park in Ridgely. Positioning themselves in the arboretum's forest within hearing distance though not necessarily within sight of each other, the musicians will respond to each other's playing in a musical conversation that winds through the trees. Afterward, they will give a brief concert in the Visitors Center. The program is free, but registration is required and seating is limited.
