Brenan paints landscapes, portraits and abstracts in both oil and acrylic. His style tackles Pop Art and Fauvism with the whim of his brush, and an occasional statement thrown in for good measure. Re-invention is the key to staying fresh, and he tries to do so with every new show. His work has been on display in Chicago and in Nashville at these fine establishments (among others), Pre-To-Post Modern gallery and furniture store, The Mark English Gallery in Franklin, The Trace, JJ’s Market, Rumba, Jackson’s Bar & Bistro, 3rd & Lindsley and 12th & Porter.
