After attending the preview of Alexandra Metcalf’s current exhibition, “1st Edition,” at Ginny on Frederick in London, I asked a friend who had accompanied me for his thoughts on the show. “I love it,” he replied without hesitation. “It’s like a teenage girl’s bedroom. It’s so emo.” Having weathered adolescence during the early aughts, when the term “emo” first sprouted into existence, I could relate, as I had been, in many ways, that “emo teen girl” of the very kind my friend was referencing.
