How does music resemble food? How can sound work like medicine? To treat chronic digestive pain, producer Ross Simonini tried everything until visiting hypnotherapist Daniel Ryan, who uses only the sound of his voice through a technique shared by orators, monks, musicians, parents—and magician David Blaine.

We also learn about the psychoacoustics of lawn sprinklers with Susan Rogers, a sound engineer who’s recorded albums for David Byrne, Barenaked Ladies, Tricky, and, most famously, Prince’s albums Purple Rain and Sign o' the Times. Rogers is one of the most legendary female sound engineers in an industry long dominated by men. These days, she’s also a professor at the Berklee School of Music, where she researches how our brains process sound.

Lastly, author Eugene Lim brings us speculative fiction on the interstellar connections between celebrity CEO Elon Musk and the Organist podcast itself.
