Conceived when an older KC Underwood was hired to give high school student Alice Costelloe guitar lessons, Big Deal officially became a band in 2010, when Costelloe had progressed enough in her guitar work. With topics centered around school, and sparse arrangements consisting solely of two guitars and two slightly reverbed voices, the music of Big Deal seems to be innocent and delicate dream pop upon first listen. With further listens, however the evident undertones of lust come through, spawning certain critics to dub Big Deal's music "Lolita pop." Whether this term is complimentary or insulting, the duo still seems to be gaining notoriety in its native London and has consistently been heralded as 'the band to watch.'
