5 Art Openings in London this week.

London galleries are launching a packed week of late-January exhibitions, featuring solo shows by Jessica Rankin at White Cube (embroidered paintings and works on paper), R. Crumb at David Zwirner (a survey of his six-decade career in countercultural drawing), Alexandra Christou at Sadie Coles HQ (rarely seen 1990s paintings of Greek life), Christina Mackie at Goldsmiths CCA (interdisciplinary installation), and a group show 'Geometry in Motion' at Stephen Friedman Gallery (exploring geometry and seriality).
