Hi Keberoxu,
I had the privilege of auditing a master class Axel Schiotz gave
at the University of Colorado in the 1960's. Even with the severe
damage, he sang with great expressiveness and beauty. A marvelous
teacher.
In addition to his time at the University of Colorado, he taught
at San Francisco State College, University of Minnesota,
in Toronto, and Copenhagen.

For those interested in classical singing, his delightful and informative
book is well worth seeking.
