The artists in this week’s gallery picks experiment with lines in surprising and playful ways.

*            *            *

1. Robert Irwin has produced eight works that advance his use of fluorescent light, a material he first used in the 1970s. Irwin installs rows of columnar lights, coating the different tubes with colored gels that alter the transmission of light. Other tubes remain unlit taking some advantage of the reflected light at Pace Gallery
2. American artist Lloyd Martin, known internationally for his rhythmically constructed abstract painting, continues his engagement with color and line in this outstanding body of work at Stux Gallery
3. By employing gravity to manipulate printmaking grounds, Ian Davenport’s graphic works produce images that reflect the result the artist has achieved in his glossy pour paintings. The artworks continue his process-based investigation of the paradox between chance and control, the industrial and organic at Pace Prints
4. Hattie Stewart’s Adversary will take on glossy advertising imagery with Stewart’s characteristic homage-meets-satire approach at House of Illustration
5. Jimi Gleason’s silver deposit surfaces act as enigmatic mirrors that are activated by the viewer and the environment they are situated in. Light, color and form are injected into the paintings via the external world – through this movement, Gleason hopes to induce a meditative experience for his viewers at William Turner Gallery
6. Dipping and undulating lines make reference to animal and human body contours only to be interrupted by sharp turns that deny their voluptuousness in Josh Dihle’s work at Valerie Carberry Gallery
