Since bursting onto the global scene in 2004 with !WOWWOW!, the optimistic south London art collective he founded, multidisciplinary artist Matthew Stone has made waves with everything from body-littered stage performances and editorials for magazines including Dazed and i-D, to colorful, digitally manipulated impasto paintings—the chosen medium for his latest exhibition at London's Somerset House.

In a new self-directed film, the self-proclaimed art shaman walks us through his recent practice, his difficulties facing a bout of Chronic Fatigue Syndrome, and revisits ideas explored in his 2004 manifesto on the power of positivity and optimism's potential as a catalyst for change.
