As part of the Smart Museum of Art's symposium Of Hospitality on May 5, 2012, Alison Knowles conducted performers in a performance of The Identical Lunch Symphony. Building on her classic 1960s Fluxus scores, the performers used blenders to mix the components of the Identical Lunch—a tuna fish sandwich with butter and lettuce, no mayo, and a cup of soup or glass of buttermilk—which was then served to the audience.
