The sheer size of ‘Wandering Songs I (Canti errabondi I)’ from 1983 makes it a standout in ‘Mario Merz: Major Works from the 1980s’ at Sperone Westwater Gallery on the Lower East Side. The Arte Povera artist’s natural materials abound in an oil painting of leaves and pine cones on a 25’ long canvas, accompanied by a block of beeswax formed around a tree branch. The contrast between nature depicted (the painting), sampled (the branch) and made (wax made by bees) gives the piece its energy. (through Dec 22nd).
