Levi "Doctor Octoroc" Buffum ( ) is an American chiptune musician and pixel artist based in Philadelphia. It draws influence from 1980s pop culture and beyond, primarily video games from console systems made by Nintendo, the artist initially gained notable Internet recognition in December 2008 with his chiptunes album of Christmas songs arranged in the style of different Nintendo Entertainment System (NES) games, entitled 8-Bit Jesus. The album was originally made available on December 8, 2008, as a free nine-track download from DoctorOctoroc.com, as an extension of the track that Doctor Octoroc contributed to the Foundation 9 Holiday Card, featuring ten other chiptunes artists, including 8-Bit Weapon and ComputeHer. After the small collection of tracks appeared on sites like Kotaku, Joystiq, Boing Boing, and Destructoid, Doctor Octoroc created nine more tracks for an even eighteen tracks total, which he posted to his blog on December 22. The complete physical album became available in a 6-panel digipak, designed by Jude Buffum, and includes an additional bonus track titled "Let It Snoki Doki Panic". He later made a name for himself as a freelance artist, creating 8-bit and 16-bit parody animations, most notably his re-imagining of the Internet sensation Dr. Horrible's Sing-Along Blog (original film by Joss Whedon) as a theoretical NES game. Dr. Horrible's Sing-Along Game was released in April 2010 and since then, Buffum has created similar works of animation based on Twilight, Jersey Shore, Glee, Harry Potter, Doctor Who, and Man Vs. Wild. Music As a chiptunes artist, Octoroc uses a modded NES control deck as an instrument via MIDI CC signals that manipulate the console's hardware. He also composes tracks using soundfonts ripped from Super NES and Genesis games.
