Art is all about experimentation—with media, material, space, time, and maybe even some hallucinogens. This week's art round up celebrates all of those fearless wanderings into the no man's land of creation, where artists like Joe Roberts channel drug experiences into cartoons and Ragnar Kjartansson attempts to make a pop song palpable. We take a look at the launches of experimental exhibitions including the nighttime mural maze of After Hours 2: Murals on the Bowery without forgetting to honor the ground-breakers such as Jean-Michel Basquiat and Blinky Palermo.
