Capella Bach (Bach Chapel) is a chamber choir born within the Societat Bach of Sant Miquel dels Sants. It was created in 2009 with the initial purpose of singing at the closing concert of an introductory course in early music organized by the Societat Bach, and soon the singers theirselves decided to give continuity to the choir with the aim to perform and promote this kind of music.

In 2014 a major renovation of the members of Capella Bach was carried out and Murat Khupov was appointed conductor of the choir. Currently the Capella Bach has fourteen singers. While maintaining the original repertoire, primarily from the Renaissance and Baroque, some more modern works have been added, always with an intimate and spiritual character. As is proper of chamber choirs, the Capella Bach every time pays particular and significant attention to improving individual and ensemble techniques, pursuing a result of great musical beauty.
