The Bronx Museum of the Arts has long distinguished itself by its commitment to the communities that surround it, with its three-and-a-half decade Artists in the Marketplace (AIM) program a leading example of this dedication. The program assists emerging artists of varying degrees of seniority and experience with the more practical aspects of life as a working artist, and has produced a small coterie of notable alumni. Initially conceived as a means of training, the museum began tapping its AIM cohort for a biennial exhibition six years ago, and the latest iteration of this effort, “Bronx Calling: The Third AIM Biennial,” is now on view. Curated by the Bronx-based artists Laura Napier and Hatuey Ramos-Fermín, the biennial is a dizzying mixture of styles and mediums, comprising the work of 72 artists of varying backgrounds and interests. We spoke with Napier and Ramos-Fermín about their approach to the third AIM biennial, and how they sought to bring two classes of AIM participants — from 2014 and 2015 — into the public eye.
