In 2010, Nick Didkovsky’s friend, Chuck O’Meara, sent him an email with a cryptic subject line. The email had a small picture of an unbranded red guitar that had a price tag of $100. They joked about splitting up the cost amongst friends and letting everyone use it to record their own projects. Before they owned the guitar the word spread and they had dozens of people committed to the idea of recording with it. Find out how this inexpensive guitar went from being a joke to traveling the world with the $100 Guitar Project.

You can purchase the $100 Guitar Project Two-CD set to benefit CARE at this link. All selections from this episode were featured on this compilation.

Correction: In this piece we refer to Greg Anderson’s song as “Bale Wagon Blues.” The title is simply, “Bale Wagon.” We regret the error.

A mysterious 52 Hertz signal was first heard in the North Pacific in the late 1980’s. It had the characteristics of a whale call, but it was a higher frequency than what is typical for baleen whales. After years of detecting the signal on hydrophone recordings, scientists have still never seen the whale and are unsure whether it’s a hybrid species or a blue or fin whale that has a problem with its sound production. The 52 Hz whale has often been referred to as “The World’s Loneliest Whale,” because people think that other whales couldn’t understand it’s unique call. Learn more about the 52 Hz whale, underwater communication, whale tracking, and why this whale may not be as lonely as previously assumed from Darlene Ketten of the Woods Hole Oceanographic Institution, Bruce Mate of Oregon State University’s Marine Mammal Institute, and Orla O’Brian.

Read William A. Watkins’s 1999 and 2004 papers mentioning 52 Hz or click here to find an online memoriam for this man who helped discover an share the earliest information on 52 Hz.

Bruce Mate will be assisting with the documentary titled, “Finding 52: The Search for the Loneliest Whale in the World.” The search for 52 Hz will begin next fall.

As we noted in the episode, “Jenny Haniver” is a pseudonym. That was the name given to an airship in the Mortal Engines Quartet book series by Phillip Reeve. Jenny Hanivers also refer to dried out skates or rays that sailors would try to make into mermaids or other forms and sell to other sailors and tourists.

If you’re so inclined, here is what a Jenny Haniver looks like:
