Elsa Grégoire, born in Belgium, brought up in New Orleans, and now living in Germany has a natural passion for languages and the expression with words. She studied the violin, the cello and later obtained her Bachelor's degree in jazz singing with David Linx at the Brussels Royal Conservatory. She participated to many workshops with artists such as Diederik Wissels, Michael Blake, Scott Colley, Tim Berne and Bill Carrothers. After a year at the CNSM of Paris, she moved to Leipzig (Germany) where she started developing various musical projects, including "tremula", for which she has been composing and writing songs. The first album of the band was just released in June 2014 and is entitled "I Sing Because".

She is the co-founder of the a cappella sextet "Brussels Vocal Project" which recently recorded an album featuring original music exclusively composed for the band by some of the Belgium's most famous composers. Performances of minimalistic music in the "Centre Pompidou" in Paris and her stand as the front woman for the african-worldmusic band "Liloba" reflect the width of her interest and competence in a large variety of musical worlds. Elsa has just recently finished her Master's degree at the Hochschule für Musik Carl Maria von Weber Dresden.
