"Chicago-based Tiny Fireflies has been making sweet shimmery beautifully layered indie pop for some time now. Under the quiet bedroom recordings of Lisle Mitnik and Kristine Capua, the duo had eventually grown out of those covers and have recorded some of the most exquisite indie pop gems on this side of the Western Hemisphere."

Tiny Fireflies began as a collaboration that did not have any intentions of being a band. Chicago musicians Lisle and Kristine (whose solo projects are Fireflies and Tiny Microphone respectively) were asked to appear on "Between two Waves," a compilation series driven by the concept of two musicians joining forces to create a song together, for netlabel Eardrums Pop.

Their song ʻDonʼt Wait Until I Fall Asleep," an homage to the Factory Records sound, was an instant fan favorite among Eardrumsʼs four compilations, and in October 2010, Tiny Fireflies became the first band to release a single for the label's singles club. The three-song single was voted favorite Eardrums release, favorite single ("Snow"), and favorite collaboration in the year end poll.

The duo played their debut show in May 2011 at the 5th Annual New York City Popfest. They have since played in England, Spain, and around the Midwest (opening for Memoryhouse) in support of their follow-up EP "Change," which was released by Spanish label Little Treasure in August 2011. (It sold out in less than two weeks.) Cloudberry Records released their follow up single, "Picture Perfect" in Mach, 2012.

The band's debut full length, "The Space Between," was released in November, 2015. Produced by Ian Catt (Saint Etienne, Trembling Blue Stars), it has been described as "some of the best retro synth pop around in 2015" by AllMusic, and "a delicate bit of gossamer synth-punk that floats like cloves smoke out an apartment window" by CMJ.
