Kate Nash is an English singer-songwriter. She was born in London to an English father and Irish mother; she grew up in Harrow, North London. Nash became interested in music during her childhood. She learned how to play the piano at Sandbach School. She attended St. John Fisher School (in Pinner) and moved onto the St Joan of Arc Catholic School, Rickmansworth. She was taught guitar by teacher Louis Michelle. She studied Theatre at the BRIT School for Performing Arts and Technology in South London. She auditioned at the Bristol Old Vic Theatre School but was rejected. Nash decided to focus on her songwriting: she began to write some new songs, finished old ones. She subsequently decided to start a career in music. After several gigs, Nash uploaded her music to the social networking website MySpace.

Nash's début was a single—Caroline's a Victim/Birds—produced and recorded in Iceland by Valgeir Sigurðsson and released through Moshi Moshi Records in February 2007. The release was limited to 1000 copies, and was available on only 7" vinyl. Due to demand, another 1000 copies were made and sold out. A video for the song was released and received airplay on MTV2. The video was directed by Kinga Burza. The B-side, "Birds", later featured on her debut album, Made of Bricks.

In April 2007, Nash was signed to the Polydor offshoot Fiction Records. Nash's second single and first through Fiction Records, "Foundations", which she co-wrote with producer Paul Epworth, was released on June 18, 2007 and reached number two in the official UK Singles Chart.

Following "Foundations", Fiction announced plans to bring forward the release of Nash's debut album to August 6, 2007. The album, Made of Bricks, produced by Paul Epworth, included many of the tracks she had been performing on her two nationwide tours. The album reached number 1 in the UK charts.

During mid-2007, Nash performed at numerous festivals including Wireless Festival, Bestival, the Electric Gardens, Glastonbury, Latitude, Reading and Leeds, Oxegen and T in the Park. She made her official TV performance debut on Later with Jools Holland.
