As the name suggests, the main concept behind the "Quintet" series of exhibitions that the Sompo Japan Nipponkoa Museum of Art started running last year is to bring together five artists whose art harmonizes well, just like a musical quintet.

Another goal, according to the museum's chief curator, Masaru Igarashi, is to boost mid-career middle-ranking artists, in order to help them get their own solo shows at major art museums.

"Quintet I" took landscape as its unifying theme, and while "Quintet II: Five Star Artists," stays with that theme, it pushes it in a much more abstract direction.
