On the floor in a corner of James Harris Gallery is a rock with a party favor inserted into it. The party favor looks like a palm tree made of iridescent silver Mylar, and the party is ongoing—a light machine on the wall just above the rock casts rhythmic patterns of red and green lights, creating the transporting appearance of a tiny island of leisure, as guiltless as outer space, a place where there has been never been any destruction or exploitation, just happiness. Sol Hashemi's first solo show at the gallery is full of these moments of contact with freshly minted, unspoilable landscape. (James Harris Gallery, 312 Second Ave S, 903-6220, 11 am–5 pm, free)
