Forming in 2019, STFLR started as a hobby between high school friends that quickly turned into something more. Members of the band had been playing in various bands for over a decade, but STFLR felt special.

Since their formation in the fall of 2019, STFLR started out more as therapy than a band of lifelong friends. With the launch of their debut EP, 'Flaccid and Unused' the young Long Island trio found the release they were looking for, and stepped up their plans and recruitment.
