Julian Bliss doesn't do things by halves. At the age of ten he'd already left home to study clarinet in the United States.
This weekend, he's performing not one, but two concertos with the Christchurch Symphony Orchestra.
One is the world premiere of a new work written for him by New Zealander Ross Harris, the other is a 1940s creation by the American jazz great, Artie Shaw.
Bliss joined RNZ Concert host Bryan Crump ahead of the concert to talk about his love of the clarinet, mixing it in the jazz world (including getting a concerto out of another jazz giant, Wayne Shorter), and how he met Ross Harris, but is yet to meet his heavy metal rock idol, Ozzy Osbourne.
