Ta-coumba Aiken has been busy. Not only is he presenting new work, created in collaboration with Seitu Jones, at the Minneapolis Sculpture Garden this week, he also has an exhibition of paintings, on view with works by the fast-rising Leslie Barlow, opening at Artistry. It’s a meeting of minds a generation apart: The eminent Aiken has a reputation for dynamic, abstract motifs while Barlow creates beautifully detailed, realistic paintings. Both artists reflect different aspects of the African-American experience, multiculturalism, and otherness with resonance and relevance. Here’s an unprecedented opportunity to view two masters at work.
