Beijing artist Song Dong brings his mother’s possessions to life at New York’s MOMA. In his first solo museum show: Waste Not an exhibit running until September 7, Song personifies  frugality and a more earth-friendly thought to would- be trash. Objects that would have normally been discarded, are saved for the chance of new usefulness.  For five decades Song’s mother had amassed ropes, toothpaste tubes, shopping bags, plastic containers, broken dolls and anything else she deemed salvageable. After the death of her husband the thoughts of her meer thriftiness crossed the fine line into hoarding,  and Song convined his mother to let him help her out of her small house brimming with chaos.
