Behind the Scenes

The Behind the Scenes, or BTS, of Epic Rap Battles of History is a series of videos uploaded to the ERB2 channel which are created to show the viewers what goes on while creating the rap battles. The Behind the Scenes videos can involve interviews with members of the ERB crew, such as Jon Na or Andrew Sherman, and used to contain EpicLLOYD's heroin joke.
