[1][2] Throughout the years Sweetbox has had several lead singers including Kimberly Kearney, Dacia Bridges, Tina Harris, Jade Villalon, Jamie Pineda and most recently and currently, Miho Fukuhara and LogiQ Pryce.
Although the project released four singles in the mid-1990s, with initial singers Kimberley Kearney and Dacia Bridges, worldwide success came with third vocalist, Tina Harris.
Tina Harris left after two years, with Jade Villalon replacing her as the fourth vocalist with five original albums, all reaching Gold or Platinum in South Korea.
Kearney left the project soon thereafter to pursue other ventures in the entertainment industry including a number of hosting gigs.
In 1996, Kimberly Kearney started working with Geo once again to release an additional single, "Never Alone", although this would end the partnership permanently.
With Tina's arrival to the project, the group saw a change in genre from Eurodance to hip hop and pop-meets-classical.
It reached Top 10 positions in the charts of Austria, Belgium, the UK, Colombia, Finland, France, Ireland, Israel, Italy, Lebanon, Norway, Spain, Sweden and Switzerland.
At the end of 1998, feeling burnt out as a team, Harris left the project forcing Schmidt and Rosan to find a new replacement.
In 1999, the Sweetbox team Heiko Schmidt and Roberto "Geo" Rosan discovered and hired Jade Villalon, an aspiring singer/songwriter and actress to front the project.
The song featured back-up vocalist Mucky and was primarily promoted in Europe, although the single was also released in South Korea.
The first album with Villalon, titled Classified, was released in 2000, and featured diverse genres of pop, dance and rock, each song also incorporating classical pieces by Beethoven, Ennio Morricone and others.
The Japanese Edition of the album featured bonus tracks real "Emotion" and "1,000 Words", compositions that Villalon had vocalized for the video game Final Fantasy X-2.
In 2007, Roberto "Geo" Rosan also decided to quit his work for the project and sold his part of ownership to executive producer Heiko Schmidt.
After Villalon and Rosan's departure, Heiko Schmidt started working closely with music executive Hayden Bell, who discovered The Veronicas, and Andre Recke – the longtime manager of Hilary Duff.

On February 23, 2011, Pineda announced via her Facebook page that her new album, Diamond Veil, will be released physically on April 27, 2011, in Japan.
In the Fall of 2012, the Sweetbox website reported with a message that there would be an open casting call to find a Japanese female artist to front the project.
