Sick Day is a Chicago-based indie outsider rock band with a homemade sound and raw, honest energy. Members of the band are Olivia Wallace, Kaity Szymborski, Shrav Rhagurham, Mike Molitor, & sometimes Chaepter the cellist & Dani Jean Baptiste on violin.

They have opened for renowned acts such as Friko, Bnny, & Winona Forever. Leor Galil of the Reader wrote that they "evoke the scruffy homemade eccentricity of many of the great 80s K Records acts" and are "one of the city’s next great emerging indie acts."

Sick Day released their Overexposure EP with Brooklyn-based Substitute Scene records in 2024, and their debut full-band album is currently in the works.
