Information on the location
Menlo Park, now in the township of Edison, New Jersey, is the name of Thomas Edison's hometown and research laboratory in New Jersey on the site of an unsuccessful real estate development. While there, he gained the nickname "The Wizard of Menlo Park", as it was in his Menlo Park laboratory that Thomas Edison came up with the phonograph and a commercially viable light bulb filament. Christie Street in Menlo Park was the first street in the world to use electric lights for illumination. His Menlo Park lab has been considered to be one of the greatest laboratories ever.
Appearance in the rap battle
This is the location where Thomas Edison rapped. The water tower behind him can be seen with the word EDISON written on the front. At the end of Edison's second verse, the lights go out.
This is where EpicLLOYD rapped, starting from the line, "You manipulate your friends and then you throw them away!" It later transitioned to Wardenclyffe Tower in the next line.
