The French harpsichordist Céline Frisch, co-founder of the prestigious Café Zimmermann ensemble, offers a master class of austerity, rationality and genius based on a selection of Partites from the Clavierübung I collection by J. S. Bach, which includes rondos, minuets and sarabandes, among other dances. "While you hear them, close your eyes and let Bach, movement by movement, make us understand, once again, what the concept of infinity means," says the musician and music disseminator Joan Vives.
