Well it didn't work on my brother or sister. They both dislike jazz music. I wonder what my 2 little boys are going to listen to when they are all grown up. What I think is funny (but also very interesting) is that a freejazz record doesn't bother them at all, which makes me think that many peoples aversion against the music might be more nurture than nature.... Like when a child got to hear very structured pop music for all of his youth, when he's going to hear a freejazz record than that doesn't sound nice to him. But my sons (4 and 1 yo) hearing seem to be still unprejudiced.
That's why we could easily play Lego in the morning with Ayler's 'Truth is Marching In' shouting from the speakers. Until my wife comes downstairs with that weird look on her face of course.... Than my sons have to listen to this so called 'Coffeetime' playlist on Spotify. The horror!
