Here is a good history of music that is created from human EEG data. I've written previously about a recent competition of this type of composition, but the history goes back to the 60s.
Also showing my ahead-of-the-pack-by-a-year posting style, I wrote about beta blockers and stage fright nine months before the New York Times. (I also gave a presentation on it in 1995 as part of a graduate Brass Pedagogy class.) I'm concerned about the firing of Ms. McCain, unless she is lying about only directing her students to a physician. If she handed out the drug herself, she should have been fired. Propanolol can be very dangerous for anyone with asthma or liver problems. Thus it should only be used under the supervision of a doctor. But if she only suggested the drug and properly directed the students to a doctor, this is completely within the purview of a studio teacher. The exception I could see is if she required her students to see the doctor, which was not suggested in the article.
