In his book Hallucinations, the acclaimed British-American neurologist Oliver Sacks chronicles a wide range of hallucinatory conditions reported by his patients throughout his illustrious career. I have chosen five of those cases as the inspiration for this concerto, creating an imaginary musical representation of each mental state. These particular hallucinations were comparatively benign for those who experienced them, and in some cases were positively welcome.

Hallucinations are fascinating phenomena - instantaneous random inventions of our brains overlaid on the sensation of common reality and indistinguishable from it. Many of us will experience them in some way during our lives. When we sleep for example, we are aware that our brain is in free flight and its muddled dream scenarios are not real. On the edges of sleep however, we can confuse random mental impressions with reality, and are hallucinating. A typical example is hearing one's name spoken by an unknown person; another is when the tail end of a dream impinges on perceived reality.

Sufferers of brain damage or a range of neurological disorders regularly hallucinate. Others without mental illness but under great stress or fatigue can also hallucinate, as of course can those who use psychotropic drugs. It is this bridge between the real world and some of the surprising ways in which our brains interpret the mundane reality around us that I find endlessly fascinating.
