In November 2016 Dorothea Sahlmüller interviewed 33 voice experts for an online voice conference (affiliate link). 33 video contributions illuminate the human voice from 33 highly exciting and sometimes unusual perspectives.
I was interviewed too. My video was even voted on number 2 of the best interviews :) You will learn some phenomena that you would not immediately associate with overtone singing. Among them a new hearing test that will fundamentally change your perception of sound, experiences with dolphins and overtone singing in the Red Sea and my emotional experiences with autistic children.
The congress package with all the videos and some extras can be downloaded from Dorothea’s website.
