I caught the exhibition "Art as A Verb" on its last week at MUMA. Great selection of works surrounding the theme of action within and beyond the gallery space. There were several artists whose works I've only read about but never actually seen the documentation of the performance in a gallery setting. These artists include Tehching Hsieh (and his year long performances), Rirkrit Tiravanija (and his cooking for gallery goers as a performance), and Yoko Ono to name a few.
One artist I discovered was the Cairo-born Basim Magdy his video "13 Essential Rules for Understanding the World", 2011. I loved the simple everyday imagery that accompanied the text. Also, I liked how the text appeared to be presented as half-truths.
