Glassheart is the third studio album by British recording artist Leona Lewis, released on 12 October 2012 by Syco Music and RCA Records. The album is Lewis' first under RCA Records after parent company Sony Music Entertainment closed J Records and relocated its artists. Glassheart was conceived in 2010 shortly after the completion of Lewis' first headline tour, The Labyrinth. Recording and production took place in Denver, Los Angeles and London; originally the album was due for release in November 2011 but was pushed back several times to accommodate new recording sessions and allow more creative time.
On Glassheart, Lewis reunites with Ryan Tedder, record producer of her previous singles " Bleeding Love" and " Happy" and songwriter Andrea Martin who co-wrote " Better in Time," in addition to a number of new collaborators such as British duo Naughty Boy and Emeli Sandé, Rodney "Darkchild" Jerkins and DJ Frank E. Producer Fraser T Smith executive produced the album after impressing Lewis with his work on Hurt: The EP (2011), a cover song extended play (EP) that Lewis released to bridge the gap between Echo (2009) and Glassheart.
" Collide", a collaboration with house music DJ Avicii, was released on 2 September 2011. Originally a song by just Lewis, Avicii sued Sony Music claiming that the song plagiarised his own instrumental " Penguin". Through mutual agreement it was released as a collaboration, becoming a top-five hit in the UK and Lewis' first to top the US Billboard Hot Dance Club Songs chart. The Afrojack remix of "Collide" is the only version to feature on Glassheart. Subsequent singles " Trouble" featuring American rapper Childish Gambino and " Lovebird" were less successful, the former reaching top-ten in the UK and top-thirty in Ireland while the latter sold fewer than 600 copies in the UK and failed to chart anywhere in Europe.
Glassheart received a mixed reception from critics who praised the vocals and experimental use of dubstep and electronic music but were less impressed with the album's many ballads. In the UK, the album was Lewis' first album not to reach number one, debuting at number three with 27,000 copies in its first week. Elsewhere the album became Lewis' third top-five album in Ireland, and upon its international release in November 2012, reached top-thirty in some of continental Europe. Following a 2013 release for Austria and Germany, Glassheart peaked at number five and six respectively outperforming previous album Echo. In April 2013, Lewis embarked on the Glassheart Tour, in support of the album, visiting Switzerland, Germany and the UK.
"Glassheart" is a song recorded by British singer-songwriter Leona Lewis for her third studio album of the same name (2012). The song was conceptualised by Lewis and frequent collaborator Ryan Tedder at his family home in Denver, Colorado. As she was experiencing a stressful time in her life, Lewis wanted to create an uptempo dance track with Tedder as she felt a ballad would make her more upset. It was co-written by Lewis and Tedder alongside Brent Kutzle, Noel Zancanella, Justin Franks, Fis Shkreli and Peter Svensson. Production of the song was handled by Tedder and Franks, with the latter credited under his production alias DJ Frank E. It was co-produced by Zancanella, Kutzle and Shkreli.
"Glassheart" is an up-tempo dance song that incorporates elements of dubstep, grime and house music. Lyrically, it is about a woman's fear that her boyfriend will leave her and thus she protects her emotions and her heart from breaking. The song received positive reviews from music critics, many of whom praised the musical direction and its grimy, dubstep breakdown. Upon the release of Glassheart, the song debuted at number 27 on the UK Dance Chart due to strong digital download sales during the first week of Glasshearts release. It debuted at number 167 on the UK Singles Chart. Lewis has performed the song at London nightclub G-A-Y and an acoustic version for UK newspaper The Suns Biz Sessions.
