“Charles Long: Pet Sounds”

While it may look like Madison Square Park being invaded by alien blobs, sculptor Charles Long’s project comes in peace. A network of brightly colored pipe railings feature amorphous shapes that suggest creatures on their way down a python’s gullet. They curve around the Park’s Oval Lawn to converge on a common seating area. Running your hand over the forms produces a variety of sounds from within: That, and not some tribute to Brian Wilson, is the reason for Long’s title.
