On this episode, we look at how a 1973 New York Times bestselling book of controversial experiments on plants inspired generations of artists to try to communicate with plants through sound. We hear about what it was like to grow up with pioneering electronic musician Mort Garson, whose early synthesizer album Plantasia went from being a free gift with a mattress purchase from Sears to a $150 dollar used CD on Amazon.
