20 years after the Orchestra of the 18th Century s first engagement on tour with Bach s Mass in B minor, a work which has for so long captivated the inquiring mind and interpretative insight of Frans Brüggen, a new tour was conceived through which to provide a fresh view of the piece. Setting down a recorded view during tours has always been key to this orchestra s musical expression and last year the opportunity was taken at an exciting concert in the Polish capital of Warsaw: a city and a country with whom director and orchestra have long and treasured memories. Accompanying the CD set is a booklet essay from David Vickers which provides a scholarly and eminently-readable account of the social as well as the musical background to the composition of the individual parts of a piece whose unity has provided the world with one of its greatest works of musical art. This new recording is more than a 20th anniversary celebration, reflecting as it does Frans Brüggen s lifelong desire to understand and project the work of J.S. Bach.
