Walk into any traditional art museum and you’re likely to see dozens of oil paintings on canvasses. Sure, you might see some acrylics, watercolors, and ink drawings, but oil remains painting’s most prevalent medium. Recent MICA graduate Jameson Magrogan wants to challenge the belief that oil is somehow better in his new show, “Oil, Then Acrylic,” now on display at Transformer as part of the gallery’s annual year-end solo exhibition. Instead of stretching canvasses on thick bars, Magrogan uses thinner wood for some pieces and linen for others. He wants viewers to see the paintings as sculptures, three-dimensional objects that just happen to also feature painted images. Thematically, his works vary: One predominantly white canvas includes an abstracted beach ball while another, “It’s just too damn hot out here I tell ya” (pictured), features a sunny day in a backyard. In Magrogan’s show, the form the painting takes is just as important as what’s pictured. The exhibition is on view Wednesdays through Saturdays noon to 6 p.m., to Jan. 31 at Transformer Gallery, 1404 P St. NW. Free. (202) 483-1102. transformerdc.org.
