Flurin, you were the "baby in jazz" guy!
Man, at 13 I was a bit of a pop-sinister (Echo & the Bunnymen, the Cure, the Smiths, Joy Division, Siouxsie, Psychedelic Furs...) trying to leave that stuff apart, taking my time with 60´s and 70´s rock and hard-rock.... and starting with the blues, which leaded me to jazz...
Wish I had started with jazz before.
