Hooverphonic is a Belgian band that formed in October 1995. Though early on categorized as a trip hop group, they quickly expanded their sound to the point where they could no longer be described as a lone genre, but rather encompass alternative, electronica, electropop, rock, and mixture of others. The band originally called themselves Hoover, but later changed their name to Hooverphonic after discovering other groups were already using the Hoover name and to avoid any legal issues with the vacuum cleaner company.
On 10 October 2008, Geike Arnaert, the lead singer of the band, announced she would leave the group by the end of the year to pursue her solo career. Arnaert had been working on solo material for a few months. The last concert of Hooverphonic with Geike was on 13 December 2008 in Tele-Club, Ekaterinburg, Russia. It was filmed by the local MTV station and was shown on Russian TV in 2009.
On 29 October 2010, Hooverphonic announced their new single on their website. The videoclip showcased fourteen possible singers but only one of them, Noémie Wolfs, proved to be the real successor of Geike Arnaert. On 4 November 2010, the new singer was announced on De Laatste Show at the VRT, the Flemish public broadcasting organization.
On 26 March 2015 Hooverphonic announced that Noémie Wolfs would be leaving the band "in mutual agreement".
The original members of the group were vocalist
Esther Lybeert, keyboardist Frank Duchêne, bassist Alex Callier, and guitarist Raymond Geerts. Lybeert recorded several demos with the group; however, she backed out of the band on the day they were to sign their contract with Sony Music. The band then brought in Liesje Sadonius to record the album. Sadonius left Hooverphonic on amicable terms shortly after the release of A New Stereophonic Sound Spectacular.
Kyoko Baertsoen, singer for fellow Belgian trip-hop band Lunascape, filled in for Sadonius for three months of a European tour in 1997 before Geike Arnaert was made the permanent singer later that year.
Additional session musicians for Stereophonic include Eric Bosteels, a session drummer with Hooverphonic from 1997–98 (replaced by Mario Goossens until 2005) and David Poltrock, a keyboard player from the group on-and-off from 1998 until 2005. In 1998, Hooverphonic also contributed to the Depeche Mode tribute album For the Masses, with their cover of "Shake the Disease".
