David Drum’s Moss is a powerful abstract painting built through vigorous gesture and layered colour. Deep blues and greens dominate the surface, evoking organic growth and damp, forest-like density, while broad sweeps of white cut across the composition, creating a sense of motion and disruption. Dark, almost column-like forms anchor the centre of the painting, giving it weight and vertical tension, as if the imagery is pressing upward through the surface. Sharp accents of red, along with small flashes of yellow and ochre, puncture the cooler palette, introducing energy and emotional urgency. The varied paint handling—thick impasto, drips, splatters, and translucent passages—adds a tactile intensity that reinforces the work’s expressive force. Rather than depicting moss literally, the painting suggests its presence through rhythm, texture, and accumulation, conveying growth, pressure, and vitality in an abstract, visceral form.
