“Choose one idea and stick with it no matter what” was decent advice for an artist until a couple of decades ago. Dahlgren took this to heart and spent his career rearranging stripes of colour with a dedication that would put Daniel Buren to shame. He has produced stripy prints, sculptures, videos, and photographs. He has even staged a series of colour protests filled with placards designed to his colour scheme. He probably makes his own t-shirts which, of course, are always striped.

I met Dahlgren in his studio over a decade ago and even then wondered how and if his practice might develop. It seems that it hasn’t. But should it? In this anxiously posed show, the works are older than the artist’s last good idea, and nothing strives for novelty not already synonymous with modernity. If only Dahlgren’s proposition was any more daring, disordered, or simply counterintuitive, the gallery might be spared waiting for his stripe to enter the canon.
