"Bat Country" is a single by the American har rock band Avenged Sevenfold from their 2005 album, City of Evil. The song's main influence comes from Hunter S. Thompson's 1971 novel Fear and Loathing in Las Vegas, and the title itself also comes from a line from the book in which Raoul Duke, the alter-ego pseudonym of Thompson himself, is on his way to Las Vegas while being affected by various drugs, and thus hallucinates, seeing huge bats and manta rays in the sky. With this, he screams to his companion, Dr. Gonzo, "We can't stop here. This is bat country."
