One of the most frequently mentioned "favorite" works of Bach, the B Minor Mass is not really a functional liturgical work, but an assemblage of movements written over a period of many years. Its grand scale is certainly awesome, but its musical and spiritual unity is more remarkable, considering its origin and the fact that it contains several different compositional styles--not to mention some of Bach's most profound and beautiful music. Performing this work and preserving a sense of its grand design while bringing out the considerable musical details is a challenge that most choirs, orchestras, and conductors are not up to. Almost by consensus, however, John Eliot Gardiner's version is the most successful--and it is indeed a phenomenal recording--at once sumptuous and penetrating, with gorgeous choral and solo singing, and spacious, vibrant sound. --David Vernier
