Adam McEwen (b. 1965, London, England) walks with his head hung low, not in sorrow but in study, charting the humdrum topography of a city’s streets—its strata of gum once-chewed, crags of cigarettes once-puffed, and rivers of coffee or urine or maybe some unknowable juice. Sidewalks presents a selection of 51 inkjet-on-sponge paintings alongside the ambient poetry of Tan Lin.
