Rivers of the Mind is a psychedelic Urban Fantasy/Superhero audio drama set in the Texas Hill Country. It centers around an underground laboratory concealed underneath a water treatment facility--formerly a part of the MK Ultra program, but today used to test secret technology for space travel. It's first main character, John is a homeless geologist who takes LSD outside of the lab one night and develops the ability to read minds, who is eventually joined by Meagan, a cashier at Walmart who receives "The Gift of Language" from a field of psychedelic mushrooms, and Sapphire, the ghost of a test subject who died in the 1960s. The show also features a "show within a show" following a police officer whose memory was erased by John just as he developed empathic superpowers, and an internet conspiracy theorist trying to help him discover the truth.
