“The Blue Tree” is presented as a single, distilled moment within Sam Lock’s ongoing exploration of mark, structure, and interruption. Here, a light grid formed by different elements acts as its quiet framework against which a concentrated burst of gestures erupts. The work feels at once constructed and disrupted: the calm of the underlying linearity meeting the restless energy of the painted marks, crossing each other between background and foreground.
Lock’s characteristic sense of loss and erasure remains present, not as a narrative, but as an atmosphere. The grid suggests something once whole, measured or mapped, while the vivid blue rises like a tree not yet grown to its full extent, fragmented, abstracted, and reassembled through gesture. The painting is a self-contained visual thought that hints at a larger sequence.

Sam Lock paints viscerally. Using blowtorches and sanders as well as the brush, he sees each canvas as a battlefield. Sanded, stained, scorched, and sealed, each work is the result of a continuous cycle of making–a repeated process of building up and destruction. The works have an elusive feeling, revealing layers of past images and tones that drop in and out of themselves. This sense of painterly archaeology brings attention to the movement of the mind and the residue of action, and the pervading sense of unpredictability. The physicality of Lock’s process is evident throughout his paintings. His expansive gestures and sweeping movements on a monumental scale as well as his smaller works, where marks made by the movement of the wrist are added to paper, translate into an energetic artistic presence visible throughout his works.
