This YouTube channel features a series of videos featuring real-time MRI movies acquired at the Max Planck Institute for Biophysical Chemistry in Gottingen, Germany. The videos are fully narrated by both Mr. Epstein and Dr. Iltis. Mr. Epstein, former 2nd horn of the Cleveland Orchestra, and now on the faculty of both the Boston Conservatory at Berklee and the New England Conservatory, places a much-needed emphasis on interpreting these MRI videos through the eyes of a master teacher of horn. Dr. Iltis, Professor of Kinesiology at Gordon College (also a former horn player), is responsible for conducting the research that generates these films, and shares his scientific perspective on the films. Together, these men provide a well-balanced and disciplined approach to understanding these amazing images. They have presented this work in 2 consecutive years at the International Horn Symposia held in Los Angeles (2015) and most recently at Ithaca College (2016).
