This album is a re-release of Hänssler Classic's celebrated Bach Ein Choralbuch series, which recorded all of the master composer's choral works. The present release features chorale settings for Easter, Ascension, Pentecost, and the Trinity. The Bach Collegium Stuttgart was founded in 1965 by Helmuth Rilling as the instrumental partner for the Gächinger Kantorei, and has been administered and funded by the Internationale Bachakademie Stuttgart since 1981. The group's complete recording of the sacred cantatas and oratorios of Johann Sebastian Bach, released during the composer's 300th anniversary year in 1985, raised it's profile as a leading Baroque music ensemble performing in a historically-informed style. Nevertheless, the Bach Collegium mainly performs on modern instruments. In this way, it can constantly expand it's repertoire and it is now a highly flexible orchestra which is capable of expertly performing works of all periods. Numerous recordings, particularly those on the Bachakademie's own label Hänssler Classic, including several premieres, illustrate the group's versatility.
