"He asked me if I wanted to play again that summer, but I was going to Sydney," Yu recalls. "Eckehard then told me that the Australian trip could potentially be more beneficial. All I had to do was win and he'd invite me for some more performances, and it's turned out to be in Auckland."
Currently based in Berlin, Yu is relieved the German capital is "quite tolerant of foreigners", as he has been invited to perform by both the President of Germany and the Speaker of the House. "Who wouldn't be happy in a city with seven professional orchestras and four opera houses?" he asks.
Yu's German background was useful in China with the Tianjin Symphony Orchestra earlier this year.
"A lot of the musicians studied in Germany and I was able to talk with them in German - proof that, in the symphony hall, the world is indeed becoming smaller and smaller."
Two years ago in Sydney, Avan Yu carried off the prize for the best performance of a work by Ravel, which augurs well for Thursday's concerto. The French composer fascinates the Canadian pianist. "Ravel was a perfectionist. He was fascinated by inventions and machines and, early on, he must have realised that the piano was such a wonderful machine to create magical sounds."
When we turn to Thursday's concerto, Yu talks of how Ravel expects the pianist "to come up with the sonorities and textures of three hands with just one. It is absolute genius how he, as a composer, can create all those layers with only five fingers."
Next Saturday, Yu can also be heard in recital at Auckland Museum, playing Beethoven and Schumann on its Fazioli piano. Interestingly, the Canadian carried off a special award for playing Beethoven at Sydney in 2012. Two sonatas, the Appassionata and the Opus 110, have been carefully chosen.
"The Opus 110 is a very spiritual work, almost religious. At one point, early on, Beethoven writes that the music is dying. Then there's this resurrection and it ends on a glorious and positive note."
He sums up the celebrated Appassionata as "a very dramatic story that ends in disaster", referring to its storm of a Finale. "One is a middle period work, the other one of the last three sonatas. I like that and it's fascinating to hear how one composer can achieve so much with the same musical language."
