Let Me Hear is the opening theme of Parasyte, the anime adaptation of Hitoshi Iwaaki's manga about a teenager sharing his body with an alien parasite. Performed by Japanese band Fear, and Loathing in Las Vegas, the song pairs the series' tense, unsettling tone with a loud post-hardcore sound. After the anime aired, fans reused the opening in AMVs, edits, and soundboards, and it became shorthand for Parasyte itself. It remains popular because its instantly recognisable intro works as a high-energy cue for action and transformation scenes.
