Big Deal is the project of native Californian Kacey Underwood and North Londoner Alice Costelloe. They were each playing in different bands when Costelloe's mother, who worked at the school where Underwood was teaching music, suggested that the pair play together. After releasing a handful of singles, the duo's intimate debut, Lights Out, arrived on Mute in 2011. Costelloe and Underwood drafted a pair of friends to make Big Deal a quartet for their second album. Produced by Rory Attwell, 2013's June Gloom borrowed from the noisy and dreamy sides of '90s rock. While making their third album, the self-funded Say Yes, the band parted ways with Mute and had to start from scratch when the laptop containing their demos was stolen. Recorded in ten days, Say Yes was released in June 2016 on Fat Cat.
