Boy (stylized BOY) is a Swiss–German pop duo founded in 2007 by Swiss singer Valeska Steiner and German bassist Sonja Glass. The two met while at a pop-music course at the Hochschule für Musik und Theater Hamburg in 2005. The band initially played concerts exclusively, before being discovered by and signed to Herbert Grönemeyer's label, Grönland Records, in 2011.
Their debut album, Mutual Friends (Gold-certified in Germany), was produced by Philipp Steinke and released in the autumn of 2011. The band sings entirely in English in a style reminiscent of that of Leslie Feist.
In the UK, Mutual Friends was released by Decca in June 2012. The North American release of the album was in February 2013 on Nettwerk Records.
Boy won the Hamburg Musician Prize HANS in 2011 in the category Hamburgs Newcomer of the Year, and their album Mutual Friends won the 2012 European Border Breakers Award (EBBA).
The duo's song "Little Numbers" was also featured in the Lufthansa Airline's Business Class advertisement in mid-2012. In 2013 the song was at No. 4 in the Japan Hot 100.
The duo's first-ever USA tour launched on March 1, 2013 with a sold-out performance at Joe's Pub, New York City.
After a two-year hiatus to focus on song-writing, the duo released their second studio album We Were Here in 2015.
The first new music in many years, a song called "Fit Back In", was announced to be released on May 28th, 2021.
