Matthew Collings interviews painter Gary Wragg about his work which is on view at Clifford Chance, London, through May 2, 2014. A catalogue raisonné of Wragg's paintings, Constant Within The Change: Gary Wragg: Five Decades of Paintings (John Sansom & Company) has also just been published.

Wragg comments: "…one of the problems people have when they look at painting is that they are full up to the brim with notions of what painting is and what it should be, and meaning, and so on, and so on. And the answer is – and I think that this is what every individual should strive to do – is to empty out completely, let it all go and try not to have expectations of anything, but just to actually look, and look, and look. You might respond to it in a way that surprises you, because you let it in, because you are empty; but if you are full up it means you have resistance and you will keep it out, and you will be limited. If you are less limited you can go much further."
