Not Your Father's Audio Museum Tour

You know when you go to a museum and they have those headsets for rent? You put them on, and you get some little pre-recorded audio tour. Through Nov. 14, the DeCordova Museum and Sculpture Park in Lincoln is offering something a bit more 21st century. The sculpture park there consists of 35 acres of grassy hills and trees, with about 70 modern and contemporary sculptures. Radio Boston’s Adam Ragusea brought his iPhone and checked out a new, real-time audio companion: Halsey Burgund’s “Scapes.”
