" Daniel Levitin is one of the world’s leading experts on how music influences the brain. He would be appearing with the conductor Edwin Outwater and the Kitchener-Waterloo Symphony Orchestra, which would play Beethoven. Levitin would explain how the music was affecting the audience’s collective brain. Levitin was no disinterested academic. He had had a serious career as a musician, performing with Sting, Mel Tormé, and Blue Öyster Cult, consulting with Stevie Wonder and Steely Dan, and having been recording engineer for Santana and the Grateful Dead. Then he—like Kahn—made a big switch and become a research psychologist, investigating how music interacts with the brain. He was now head of McGill University’s Laboratory for Musical Perception, Cognition and Expertise and author of This Is Your Brain on Music. "
