She soon adopted the stage name “Carisma” and performed as a featured artist on DJ Sammy’s
music. In 1996, they released their first singles “Life is Just a Game” and “You Are My Angel”, which was their first
hit. In 1997, with the release of their third single “Prince of Love”, they scored a Top 30 hit in Germany, followed by
the singles “Golden Child” and “Magic Moment”. DJ Sammy’s debut studio album Life Is Just A Game, which heavily
involved van der Kolk on vocals, peaked at 62 in the German album chart. In the Summer of 1998, van der Kolk
came up with a new project called Loona (leaned on the Spanish word “luna” for “moon”), also produced by DJ
Sammy. Originally started as a Duo, DJ Sammy stayed in the background for music videos and cover arts. The first
single, which also appeared as a bonus track on Life is Just a Game, was a cover of Paradisio’s song “Bailando” and it
became the summer song of 1998 in Germany, reaching the number 1 of the German charts 8 weeks long and
Echo-awarded as “Best International Dance Single”. By Autumn, it was followed by another single “Hijo de la Luna”
(a cover of the Spanish band Mecano) which also reached number 1 on the German charts. These two singles sold
millions and became gold- and platinum selling records in Germany, Austria and Switzerland.

In 1999, Loona’s first studio album titled Lunita was released, followed by the third and final single from this album,
the Top 30 hit “Dónde Vas”. Afterwards, the song “Mamboleo”, a cover version of Herbert Grönemeyer’s song
“Mambo”, was released from the second album Entre dos Aguas reaching #5 in German single chart. It was Echo-
awarded as “Best Dance Single” in 1999. Due to a lawsuit set up by Herbert Grönemeyer for infringement, a second
black and white music video was shot, and finally both videos were banned from music stations and only played for
just one day of airing. The song itself then had to be removed from Entre dos Aguas, the re-issued versions of the
album do not include the track and only can be found on rare and early pressings. Still the song re-appeared and
included on Loona’s first compilation album Greatest Hits later in 2000. Entre dos Aguas saw three more single
releases “Salvador Dalí”, another cover of the Spanish band Mecano, “La Vida es una Flor” and the Christmas single
“Navidad”, becoming minor hits which did not reach the Top 50 in Germany. In 2000, Loona’s first compilation
album Greatest Hits and its first single, “Latino Lover” (a Spanish remake of “You’re the Greatest Lover” by the pop
band Luv’), was released and peaked at #6 in German and Swiss single chart. In 1999, van der Kolk again provided
guest vocals as Carisma for DJ Sammy’s single “In 2 Eternity” from his first remix album DJ Sammy at Work (In the
Mix).

Night” and “Colors” from the third studio album Colors. For this album, Loona experimented with a more mature

moderate hits. The album is a collection full of cover versions. According to van der Kolk, she dedicated the album
title, selected track list and the entire album to her mother, whom she lost ten years ago. It features covers such as
Procol Harum’s “A Whiter Shade of Pale”, Peter Sarstedt’s “Where Do You Go to My Lovely”, Ralph McTell’s “Streets
