After completing her engineering studies at the Vrije Universiteit Brussel in 1994, Caroll was determined to go forward and continue in her ambition as a musician.
She enrolled at the music conservatory of Ghent, where she finished her candidature years and prepared for her entry-examination at the famous London Guildhall School of Music and Drama. Artistic excellence and high quality performance lie at the heart of the Guildhall School's success and only a limited number of international students are accepted. She completed her postgraduate studies at the Guildhall where she graduated magna cum laude in 1998. During that time she worked together with the great Iranian conductor/composer Alexander Rahbari, who was leading the Belgian Philharmonic Orchestra
of the National television broadcasting network at that time.

In 2006 she started to write songs for her new album Colours and wanted to mix all the influences she had into one CD. There are some fantastic musicians playing on " colours' "  like Mike Roelofs, Ron van Stratum, Frank Peeters, Sam Vloemans and Henk de Laat. The cd
2008: release of debut solo full album, Colours’. In her debut solo album singer-songwriter Caroll Vanwelden brings a mix of all influences she encountered in her career as a singer. You strongly feel her passion for Jazz, Latin and Soul, melted with a dash of pop. Some songs are easy listening; others bring you to the dance floor. Her very distinctive style and her perfectionism made it long to go for a solo album.
Critic Albert Healemeersch: "Colours’ is a powerful debut of a great singer-composer. A must in your collection!"

As jazz has always been her first love, Caroll Vanwelden recorded at her home studio a collection of exquisite standards for an easy listening compilation of her all-time favourites, which resulted in the new swing jazz album ‘Cheek to Cheek’. Critic Albert Healemeersch: No horns, no violins, just that sober sound that reminds of the real cosy jazz clubs. With some of her friends and top musicians – Dirk Van Der Linden on guitar, Janos Bruneel on double bass, and Stijn Wauters on the piano – vocalist Caroll Vanwelden succeeded in recreating that lovely 1920-30’s sound with just the right retro touch and lots of great swinging moments. As a vocalist Caroll was really made to bring that good old jazzy style.

In March 2010 she performs on the gala of the Belgium-Indian Economic Mission in Mumbaï (India) headed by H.R.H. Prince Philippe of Belgium.

In January 2011 Caroll moves with her family to Germany where she starts composing for her new challenging project: putting music on 16 Shakespeare Sonnets.

Critic Albert Healemeersch: This year, she’s back again with her new album 'DON’T EXPLAIN' with her favorite songs of the ‘40s, featuring refreshing and colorful arrangements. Listening to her outstanding, unique and warm voice, you quickly come to the conclusion, that all the ingredients are there again to turn this 'new adventure' into another hit.
The openers 'All or nothing at all’ and ‘Don’t explain’ put you immediately in the right mood and atmosphere. Even the duet-song ‘Baby it’s cold outside’ keeps the listener in suspense until the last chord. Together with her wonderful band, Thomas Stabenow on double bass, Daniel Prandl at the piano and Bernhard Sperrfechter on guitars, Caroll Vanwelden takes us seamlessly back in time to the top years of the good old cozy jazz clubs.
DON'T EXPLAIN' is an amazing, powerful, emotional and vivacious album with fourteen tracks presented in a very minimalistic line-up; an album that catches your attention from the beginning to end .

In oktober 2014
: Curtain raised - Presenting Shakespeare Reloaded!
Two years ago, newly discovered in Germany, the outstanding Belgian singer Caroll Vanwelden catapulted herself into the limelight amid much celebration and acclaim.  “As a singer, pianist and perhaps most importantly as a composer she shows both original and new ways to entrance music lovers ”, enthused Mauretta Heinzelmann, “Transposing Shakespeare with minimal repetition while at the same time using complicated time changes”, the exceptional CD released in 2012 was chosen as “Album of the week” by the North German broadcasting company (NDR). Not less impressed was Thomas Hintze of Stereo, who saw in “Caroll Vanwelden Sings Shakespeare Sonnets” a project that “had the potency to be CD of the year”. As a result Stereo awarded it the commendation of "CD and Audiophile Highlight of the Month". So it's obvious that the chapter between Shakespeare and Vanwelden's not closed yet. With
“Caroll Vanwelden Sings Shakespeare Sonnets 2” the graduate of the London Guildhall School of Music and Drama presents an emotional, rich and lively collection from her “seemingly endless supply of creativity.” (NDR) Together with her congenial musicians: Thomas Siffling, whose elegant melodies on the trumpet and flugelhorn intertwine with Caroll’s expressive and emotionally charged voice, fellow musician Mini Schulz, smoothly stroking or groovy plucking on the contrabass for added texture, and new band member Rodrigo Villalon accenting the flexible rhythms with the drums and various percussion instruments, Caroll Vanwelden has once again produced a rich tapestry for jazz lovers around the world.

December 2014 she sings a Christmas Programm on a 7 days-tour with the David Gasarov Trio in Taiwan.

September 2016 After releasing five albums under her own name, this belgian musician shows her great passion for Brazilian songs on her latest album and interpreted Brazilian songs in her own and unique way.
Caroll Vanwelden has performed already in French, Dutch, English, German and Spanish. For this project, she also learned Portuguese so that she could record her favorite songs in the original language.
Since her youth, Caroll is an avid fan of Ivan Lins and Joao Gilberto, and "Elis & Tom" (Elis Regina and Tom Jobim) belongs to her absolute favorite CDs. The way how Brazilian artists play harmonically and rhythmically complex songs and always exude an effortless ease, has always fascinated her and inspired her a lot. "Brazilian music has something very cute, intimate and familiar for me, it is very intense and very sad at the same time and that’s just the way I wanted my album to sound like." discribes Caroll.
Deliberately she has therefore opted for a reduced cast: guitar, bass and drums. Carolls musical life motto "less is more" characterizes the acoustic sound of the album. The fact that the musicians know each other very well and are longtime friends is clearly reflected in the intimate and warm atmosphere of the recording.
The subtle and very musical accompaniment of Hans Van Oost supports her warm and expressive vocals, while Mario Vermandel plucks his bass in a very groovy way. Luc Vanden Bosch takes care for the accentuation of Brazilian rhythms, and uses different percussion in addition to drums which also contributes to the amazing richness of the sound of the band.
With "Portraits of Brazil”, Caroll Vanwelden presents once more on an emotional, rich and lively way, her seemingly endless supply of creativity.

July 2017
“All good things come in threes“; this must have been Caroll Vanwelden’s motivation which lead the Belgian to write a jazz trilogy around Shakespeare’s sonnets. The artist went on a musically multidimensional journey which will reach its peak but also its brilliant ending with her newest release Caroll Vanwelden – Sings Shakespeare Sonnets 3 on JAZZNARTS RECORDS on July 21st 2017. Once again, the last record of her trilogy creates an original and unique approach and this time to the most popular sonnets of the English grandmaster. The guiding thread of all productions is the warm and colorful voice of Vanwelden. One moment the artist is able to create a multifaceted melancholy and in the next moment, the listener gets carried away by the intensity and power of her voice. She releases energy, creates emotions, and enchants with hypnotic ease. This, combined with the thematic discussion on Shakespeare and his credo on the prosecution of infinite love, creates such a powerful expression as has not yet been experienced. “The motifs and guiding lines of Shakespeare are both, fascinating and universal. I see myself in all of his motifs and find a huge amount of inspiration within them”, states the musician. The pianist is musically supported by three of the most exciting and successful instrumentalist of Germany. Thomas Siffling from Mannheim, is playing the trumpet and the flugelhorn. His elegant melodies merge perfectly with Vanwelden’s unique and warm voice. The artist and professor Mini Schulz from Stuttgart is not only stroking the bow of his double bass gracefully, but is also plucking it in a groovy and casual manner. Jens Düppe, living in Cologne, is the newcomer of the group. With his drum and percussion playing, he creates complex rhythm, and contributes to the rich sound palette of the group. Caroll Vanwelden’s interpretation of Shakespeare’s sonnets no. 3 marks a magical and absolute exclamation mark behind a musical trilogy of almost uncompetitive excitement. The courageous approach and the artistic treatment of the sonnets seem to succeed effortlessly. The outcome is an album for the classical jazz admirer, friends of lyric, or the simple music fan. This album is a sheer delight from the first to the last piece, or, from verse to verse.
