Grace Bumbry issues a warning

Message received:

Dear all,
I write this message with great concern!!! It has come to my ears that there are singers who are teaching a singing method called Bumbry Method. From what I’ve heard they are crazy and wrong ideas that are far from what I would teach.
I ask you to understand that I take my work as a teacher very seriously, contributing my knowledge after 50 years of career on the stage. I would never give a letter of recommendation if I really do not believe that person is capable of doing a good job as a teacher. I know that the future of young singers depends on good teaching and that it is a great responsibility. At the moment I have not given any letter for these purpose.
Please if someone comes to you with that Bumbry Method idea, don’t believe it.
Thank you for your attention,
Dr Grace Bumbry KS
