The Griswolds formed in February 2012. The band's single "Heart of a Lion", reached #12 on the We Are Hunted emerging artists list. The Griswolds became a Triple J Unearthed feature artist after winning a slot on the 2012 Parklife Festival line-up alongside Passion Pit and The Presets. Their Heart of a Lion EP, released in 2012, received positive reviews, and helped start their touring career. After success touring in their native Australia, the band made their first live appearance in New York City on 11 May 2013 at the Brooklyn Bowl. The band began recording their debut album with producer Tony Hoffer in January 2014. The official music video for "Red Tuxedo" premiered on the VICE Noisey website on Valentine's Day, 2014. The band's song "Beware the Dog" is the first song vocalist Chris Whitehall and lead guitarist Daniel Duque-Perez wrote together. Whitehall described it as being "about losing someone we were really close with to heavy drug use. about that journey – the good and the bad times." In March 2015, the band confirmed that once they return to Australia, following their tour alongside Passion Pit, they were going to commence work on their second album. The first single off their second album, Out of My Head, was released on 12 August 2016. High Times for Low Lives, was released on 11 November 2016.
