In October 2006, Blek le Rat had his first solo U.K. exhibition in London at the Leonard Street Gallery. He participated in the Cans Festival in 2008, which featured outdoor street stencil painting in Waterloo, London by many of street art's biggest names.
His American gallery debut took place at Subliminal Projects Gallery in Los Angeles in 2008. It included paintings, silkscreen, and three-dimensional artwork, as well as photography from his wife, Sybille Prou.
Blek also had an exhibition in December 2009 at the Metro Gallery in Melbourne, a centre of street art in Australia. The exhibition entitled "Le Ciel Est Bleu, La Vie Est Belle" (The sky is blue, life is beautiful), featured wooden panels, canvas, screen-print, and photographs, tracing the artist's oeuvre from the early 1980s to the present.
Blek le Rat has nonetheless expressed the preference for the streets over galleries, stating the integrity of an artist is to be seen by as many people as possible, not being sold or recognized in a museum.
