The obvious musical reference would be splicing performance to create an uncharacteristically clean recording. A second could be using electronic software to loop or modify your sound. Another could be small breaths in irregular places creating unusually long phrases. How many sneaky ways to "deceive" an audience can you think of?
Today, I visited another branch of the ArtEZ Conservatory. The city of Zwolle is a stereo typical Dutch town straight out of the middle ages. The modern city actually dates from around 800. The structure of the school has some pretty good awe power. ArtEZ: Zwolle sits in a renovated cloister on the edge of the city center. (On the left in the picture above.) I will be posting some more pics of Zwolle soon.
Back in Enschede, I heard the finally exam (recital) of Babis Vlachos an incredible saxophone player. Besides the beastly alto playing, Babis performed one piece on the bass saxophone. This was a rare treat. Babis just finished his MM under Johan van der Linden.
