Bath Bach Choir, formerly The City of Bath Bach Choir (CBBC), is based in Bath, Somerset, England, and is a registered charity. Founded in 1946 by Cuthbert Bates, who also became a founding father of the Bath Bach Festival in 1950, the choir's original aim was to promote the music of Johann Sebastian Bach via periodic music festivals. Bates – an amateur musician with a great love and understanding of this composer's works – was also the CBBC's principal conductor and continued in this role until his sudden death, in April 1980. This untimely exit pre-empted his planned retirement concert performance of J. S Bach's Mass in B minor, scheduled for July of the same year, and effectively ended the first period of the choir's history.
