American organist and composer Cameron Carpenter is about to perform with the New Zealand Symphony Orchestra in Christchurch and Dunedin.
Cameron's been a described as a "phenomenal virtuoso". He's also been called a "bad boy rock star" - possibly partly because his 2016 album All you need is Bach topped the Billboard Classical chart, and he's the first solo organist to be nominated for a Grammy.
But mostly he plays one of the most daunting instruments there is - it occupies an entire wall of a Town Hall, it's got several keyboards that you have to play all at once, often using your feet.
Cameron Carpenter, surrounded by a daunting number of pipes, knobs, drawbars and foot-pedals. How does he do it? How does anyone do it? But Cameron has been doing it for his entire life.
