Sempre Sisters, violinist Charlotte Marckx and cellist Olivia Marckx, is an award-winning classically trained sister duo that aims to create music not limited by genre. Performing their own compositions and virtuosic arrangements of music from the Beatles to Bach, the sisters aim to play music that they love for people who love music.
