In 2012, an ex-employee of Accent Signage Systems in Minneapolis who had been let go for poor work performance returned to his former place of employment and opened fire. He killed five people at the site, and injured three others (two died later at the hospital). Local artist and curator John Schuerman knew them all. For the past several years, while running the now-defunct Instinct Gallery in downtown Minneapolis, he has curated exhibitions that take deep and unsettling dives into gun violence and gun culture. For this show in Space 369, he’s including his own piece, Counting Installation, a harrowing work that includes meticulously rendered accounts of such details as receipts for target practice, days late to work, and last words spoken. Also included are Sean Smuda’s riveting, art-historical photograph Moment of the Day, and pieces by Jennifer Davis, Michael Duffy, Ruthann Godollei, Christopher Harrison, and Jonathan Herrera. Taken singly and together, the works will leave your heart broken and intellect incited. This show is located in Space 369. Call 612-240-2317 for appointment. There will be an opening reception on Friday, October 20, from 7 to 9 p.m. Other open hours are noon to 5 p.m. October 21 and October 27.
