[3] Calderone is best known for some of his videos on his YouTube channel "331Erock" in which he performs electric guitar renditions of songs from pop culture.

Calderone's composition process started by transcribing a rough MIDI version of the melody and the tempo of the song that he wished to cover in a digital audio workstation.

After adding an element of bass and sometimes other optional instruments such as electronic musical synthesizers, he played a real time version of his cover, followed by an audio mastering phase.

[4][5] A surge in Calderone's popularity on YouTube began when he uploaded a heavy metal cover of the Lady Gaga song "Bad Romance" on October 21, 2010.

[6] He has since then uploaded some videos of himself playing well-known songs (such as the Gotye and Kimbra song "Somebody That I Used to Know",[7] the Carly Rae Jepsen song "Call Me Maybe" and the Psy song "Gangnam Style") as well as also recreating music from television shows (such as Attack on Titan, The Fresh Prince of Bel-Air,[8] Pokémon and Game of Thrones),[9] movie series (such as the three Star Wars movie trilogies and The Lord of the Rings movie trilogy) and video games (such as Super Mario Bros.[10] and The Elder Scrolls V: Skyrim).
