“It is tremendously important, this New Bach Edition – Revised of the Mass in B minor by J. S. Bach! One of the major works by J. S. Bach is now finally available in a scholarly edition, as it should be. Congratulations!” (Ton Koopman)

“Uwe Wolf has undertaken a thorough and careful examination of all surviving materials by J. S. Bach – manuscripts, paper, ink, etc. From this we will be able to gain new confidence for the individual elements of our performances.” (Masaaki Suzuki, Bach Collegium Japan)

“The NBA revised edition is an important resource now available to all performing musicians and scholars concerned to get as close to the surviving source material of J. S. Bach’s music as possible. Given the paucity of works (especially the vocal works) actually printed in Bach’s lifetime and the scattered, fragmentary or incomplete nature of the surviving manuscript sources, each new recovery (or reappraisal) acquires a special significance and is a cause for celebration. Bärenreiter-Verlag and its team of skilled editors are to be congratulated for this sustained project of reassessment for which all Bach lovers must be thankful.” (John Eliot Gardiner)
