Wacky is wonderful. Self-expression is, of course, what makes the world of art so superbly rich. On this wacky (and I mean it in the best sense of the word) tip is Sixeart’s newest mixed-media-on-paper show in Sao Paulo, Sueñan las gallinas con ser humanas (The Hens Dream About Being Human), which has specially created a baker’s dozen of new works. The Barcelona-bred artist cut his teeth with graffiti in the ’80s, but went on to scale big heights — literally — when he joined Os Gemeos and JR for the Tate Modern’s Godzilla-sized street art spotlight last year. Incorporating the influence of classic Spanish artists into his urban-style work, this latest brood addresses mutating animals, which is the last theme in a series (the first two are “bad children with fringe” and “circuits.” Miro definitely comes to mind when you see his black, bold lines dividing yellows and reds, making his chicks hot, colorful little numbers. The exhibit runs at Rojo’s Artspace until Sept. 5, but you can shop the work here.
