Theodore Waddell. With the increasing interest in modern and contemporary Western art, Theodore Waddell's Abstract Angus, curated by the DAM's Thomas Smith, is perfectly timed. From the entrance to the Gates Family Gallery, visitors are confronted by "Monida Angus," a mural so big you can't see it all until you get inside. Running across four large panels, the painting — which was specially created for this show — depicts cattle grazing in the foreground of a mountain range. Or at least that's what it looks like from across the room, because when you get up close, the cattle and scrub and even the mountains and sky are nothing more than rough and heavy smears of paint. This is true of all the Waddells here; some of them are almost non-objective, with hardly any landscape referents at all. For instance, "Motherwell's Angus," from the DAM's collection, is made up solely of a scruffy, dirty-white color field over which black dashes have been randomly inserted to stand in for the cows on a snow-covered plain.
