Why do artists work across mediums?

Often artists work spans forms, for example writers/musicians, poets/singers and so on. There are also artists who work in a variety of mediums; writers who use many different platforms, for differing audiences and purposes, or visual artists who work with oil paints and digitally. But what lies behind this adaptibility and desire to express oneself in many different ways? Do some art forms complement each other, or can the variety sometimes 'muddy' the proverbial waters? In this episode, we talk with Boris Burgess, a Hong Kong based artist, whose works span both form and medium, to explore this phenomenon a little more closely.
