Where there is great art, there is generally a great sponsor footing the bill. And where there’s a sponsor, there’s usually some tension, as artists seek to protect their creative freedom, and patrons seek to protect their financial investment. This messy arrangement is on full display at LES gallery The Hole, which is showing former Deitch artist Evan Gruzis’ “Exotic Beta,” a collection of striking paintings, multimedia installations, and video, with a heavy dose of Pop art and a dash of Dada ready-mades.
