Before making the double bass her instrument of choice, Sarah Murcia studied the piano (first at the CNR in Boulogne, then with François Bou), and the cello for a number of years. She began her apprenticeship in the classes of improvised music given by Manuel and Patricio Villaroel, later becoming a student of Jean-François Jenny-Clark. She obtained a degree in musicology at the Sorbonne and was awarded a prize in orchestration by the Schola Cantorum.
She has accompanied singers, (Charlélie Couture, Franck Monnet, Fred Poulet, Jacques Higelin, Piers Faccini, Elysian Fields) and improvisers (Sylvain Cathala, Steve Coleman, Kamilya Jubran). Some of these encounters have developped into lasting musical partnerships.
For the last ten years she has played with the Magic Malik Orchestra, and Las Ondas Marteles (Nicolas et Seb Martel).
At the moment she is a member of the groups Beau Catcheur (duo with Fred Poulet), Sylvain Cathala trio (with Sylvain Cathala et Christophe Lavergne), and Pearls of Swines (with Fred Galiay, Franck Vaillant, Gilles Coronado).
In 2001, she founded the group Caroline with drummer Franck Vaillant, guitarist Gilles Coronado and saxophonist Olivier Py. Saxophonist Guillaume Orti was added in 2012.
As an arranger, she is involved in various projects, particularly Paul Ouazon’s music programs for television and the research atelier of Arte France.
