Old Coke started in 2019 as a bedroom project, inspired by wall of sound guitars, noise rock, and energy-driven punk and metal.
Christopher Ruiz started Old Coke with the idea of being involved in the Chicago DIY scene and playing shows that cater to most of the audiences in the various music scenes in Chicago. Lyrically and vocally, he took inspiration from artists like Chino Moreno, and UK bred songwriter, producer, and musician Archy Marshall. Ruiz self-released and recorded two solo singles as a concept for what the band was to sound like, "Bottle" and "Slope." After meeting through a mutual taste of music and ideas, Ethan Toenjes joined Old Coke. From the start, Toenjes fully embraced the idea of a hard-hitting, fast, and melodic group that could transcend through multiple genres.

Despite being on a steady rise as a duo, it soon became apparent during writing and practice sessions that another member was needed, and Eddy Garcia was enlisted as the bassist to complete the trio.
