day and night in a desert, with Björk wearing the bell-shaped dress designed by McQueen, dancing playfully to the song. At some moments of the video she can be seen playing bells and holding two Siberian Huskies. Throughout the clip, several children can be seen playing bells and dressed in clothes covered in small jingle bells. The bell choir was formed by Júnia, Salka, Kaktus, Örnólfur, Daði and Gabríel of The Bústaðakirkja Bell Choir. The version of the song played in the video is different from the album version, removing almost all the vocal music and replacing it with bells. The bell-shaped dress was shown in Björk's MoMA retrospective in 2015. It was sold for £44,000, as part of Kerry Taylor Auctions "Passion for Fashion" sale in London, in June 2016. Live performances Björk first performed "Who Is It" on the 2001 Vespertine World Tour during her stops in Parma and Rome, Italy, in November. During the promotional campaign for Medúlla, a bell choir mix of "Who Is It" was performed with Rahzel and an English bell choir at BBC's Friday Night with Jonathan Ross on 8 October 2004, and at Maida Vale Studios during a set of songs for Gilles Peterson's radio show on BBC Radio 1, two days later. The song was also performed at Canal+'s L'Album de la semaine in France on 15 October, along with other tracks from Medúlla, airing some days later. "Who Is It" has been performed on the Volta Tour in 2007 and 2008. Additionally, the "Bell Choir" version was performed using the gameleste on the Biophilia Tour. Cover versions In 2011, indie band Bon Iver performed a cover version of the song during a concert in Brooklyn, New York and subsequently covered it on an iTunes live session. In 2015, Kurt Elling released a cover version on his album Passion World.
