Linda Fleming’s comprehensive solo exhibition “Confluence” at the Marie Walsh Sharpe Gallery of Contemporary Art at UCCS will feature two monumental public sculptures as well as works in steel, wood, rubber, felt, and paper. Striking here is Fleming’s enduring fascination with physics: look for the physicality of negative space, and the endless, compact lines of string theory. Opens September 6, with an artist talk at 5pm in Chapman Foundation Recital Hall.
