Though originally categorized as a trip hop group, they quickly expanded their sound to the point where it could no longer be described as a belonging to a single genre, but rather as encompassing alternative, electronica, electropop, rock, and a mixture of others.

Since their formation, Hooverphonic's lineup consisted of bassist Alex Callier, guitarist Raymond Geerts, and various lead singers.

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.

[2] The band achieved international recognition through the inclusion of the Stereophonic track "2Wicky" on the soundtrack to Bernardo Bertolucci's 1996 film Stealing Beauty.

A marked departure from their debut, the album is driven less by breakbeats and samples, and more by organic string elements and traditional song structures.

The same year, Hooverphonic was asked to write a song specifically for the opening ceremony of the 2000 European Football Championship, which took place in Brussels, Belgium.

The album tells the story of the fictional title character, a celebrity and singer catapulted into stardom at the expense of her relationship with her twin sister.

Driven to the brink of insanity by the pressures of fame, Jackie quits show business and returns home to attempt reconciliation, where her sister kills them both with a poisoned last supper.

Jackie Cane retains the dreamy elements of Hooverphonic's previous works, most notably on songs "Nirvana Blue" and "Human Interest" (which contains references to "Echoes" by Pink Floyd), but tracks like "The World Is Mine" (the first single) and "Day After Day" have a clear Broadway influence and quality to them.

In an interview for the Spanish TV program Nosolomusica, Alex Callier gave some hints of a new, more psychedelic orientation for the band's forthcoming music.

On 4 November 2010, the new lead singer Noémie Wolfs was announced on De Laatste Show at the VRT, the Flemish public broadcasting organization.

The videoclip showcased fourteen possible singers but only one of them, Noémie Wolfs,[6] proved to be the real successor to Geike Arnaert.

The band's ninth studio album, In Wonderland (2016), featured vocals from Janie Price, Emilie Satt, Litlo Tinz, Christa Jérôme, Tjeerd Bomhof and Felix Howard.

Cruysberghs provided vocals for the band's tenth studio album Looking For Stars, anticipated by the single "Romantic".

On March 21, 2024 Hooverphonic released the album Fake Is The New Dope, preceded by the singles Don't Think (2023), Por Favor (2023), Then I Found You (2023), the title track (2024) and The Best Day Of Our Life (2024).
