'My studio is a cradle of dust and dirt, of pollution. I don't tidy up at the end of each production process. It's all very much on purpose; it's [a] continuous process, a machine of which I'm the catalyst. Things get moved around, I step on them, and they get contaminated. It's not about leaving traces, it's about letting things mature on their own - like aging cheese or letting a stew cook, they get more flavorful. That's kind of how these paintings are made'
