Before the summer crowds get here (and, don’t get us wrong, we love our summer crowds!), c’mon up to Porches for an art-filled getaway. MASS MoCA has three temporary exhibitions on view that are amazing. Katharina Grosse: One Floor Up More Highly has been up since last fall. She’s known for large-scale canvases and raucous installations that employ a vibrant palette and exuberant gestures merging painting, sculpture, and architecture. Grosse opens up a new path for painting while rearranging conventions, hierarchy, and our very habits of seeing. Nari Ward’s dramatic sculptural installations are composed of material systematically collected from the neighborhoods where he lives and works or is personally connected to. By revealing the complex emotional registers inherent within everyday found objects, Ward’s work examines issues of race, poverty, and consumer culture and the inherent meaning and gravity we place upon objects from the discarded to the treasured. Nari Ward: Sub Mirage Lignum is his new installation encompassing the entire second floor of Building 4. Memery: Imitation, Memory, and Internet Culture shows the work of nine artists in the show mine the Internet – drawing on YouTube videos, pictures from Flickr or Tumblr, website logos, social networking sites, and webchat programs – examines the connections between memes (a form or concept that spreads via the Web) and memory in online culture.
