Mom Jeans found their start in early 2014 at UC Berkeley, with guitarist Austin Carango and lead singer Eric Butler. This line-up would go on to record Spring Demo in May 2014, a six-track EP which would later be released as the band's self-titled debut on cassette tape by Northern California-based label, Fourth Row Records. Tracks on Spring Demo feature only Eric and Austin in an acoustic style, while the later released self-titled EP boasted an electric instrumentation with new additions, Josh Perline on bass/vocals, and David McDowall on drums (before his departure from the band shortly after release).
