How can an artist be original?

From Keith Andrew's excellent post on Music Think Tank

"As much as technology develops and changes the world in which we live, and in many ways changes how we think, feel and interact, there are some things at the core of the human soul or psyche that will never change. And it is those deep immutable elements that will always be reached -and resonate- through art. They will resonate something of a higher truth, hope, and existence. There is something in us that always longs for and reaches for something greater than ourselves and it is art that resonates and stimulates that ‘something’."
