Sonar, and whale communication is discussed. Whales operate a utopian radio system, according to radio artist Anna Friz, and Ahab was the first shock jock according to radio artist Gregory Whitehead. We also tune in the loneliest whale in the world, who hears sounds at 52 Hz, while other blue whales sing around 15-20 Hz. And we listen to other "Moby Dick" stories, and hear from "Pistol Shrimp." Contributions from Friz, Joshua Fried, ELO, Laurie Anderson, and others.
