If you paid very close attention, you might have heard the sound of Solange Knowles’s voice cutting sweetly through the din of the FDR Drive and the blare of ambulance sirens, at Maryam Nassir Zadeh’s Spring 2018 runway Tuesday afternoon. The show, which took place on the East River Track, had been touted as “a bit of a guerrilla” affair with an unnamed special performance—“this show is in a public fitness space; those averse to workouts be advised,” read a note that went out with confirmations earlier in the week. (And, indeed, a couple older fellows could be spotted getting their afternoon constitutionals in, amid all the models.) It featured a live soundtrack by Solange, newly blonde, who, accompanied by a modest backup ensemble (a cellist, a trombonist, a guitarist), serenaded the crowd with “Rise,” a cut off her most recent record, A Seat at the Table. (She even punctured through the hum of air traffic overhead; only Solange could make a running track next to a highway feel like a sanctuary from the constant anxiety of fashion week.) Hailey Benton Gates opened for a cast that also included the likes of India Menuez and Camilla Deterre; the models, clad in Zadeh’s brightly hued separates, filed down the impromptu runway in front of an audience seated on the bleachers overlooking the track. Here, take a look inside the most comforting show of New York Fashion Week.
