I am adding my voice to the five-star reviews above.
The same compilation of J.S.Bach's cantatas BWV 80, 140, 147 and the motet BWV 227 is available in a different package as Bach: Cantatas BWV 80, 140, 147; Jesu, meine Freude. If I not mistaken, the older `Double forte' 2-CD series (see this 2-CD set) corresponds to the new `Gemini' 2-CD package.
The two recordings of BWV 140 and BWV 80 made by Wolfgang Gönnenwein in 1967 and included here, belong to the very best ones in the discography of these works. The conducting is firm without sounding pedestrian. As most conductors, Gönnenwein uses in BWV 80 the orchestration with three trumpets and timpani, likely added by J.S. Bach's son, Wilhelm Friedemann. It works here: the trumpets add the aggression in the noisy and militant first chorus of BWV 80 and are not felt as a pure decoration. The vocalists in BWV 80, 140 are excellent. The most famous of them are Janet Baker and Elly Ameling, but I would specially praise the bass Hans Sotin (unfortunately, his name does not appear on the front cover and in the amazon tags to this item): so well-trained deep voices are seldom heard in Bach's cantatas.
The recording of BWV 147 made by Geraint Jones (more remembered as an organist than as a conductor) in 1957, is not in the same league, but here you get Joan Sutherland in the soprano aria `Bereite dich, Zion'. Although this is not idiomatic Bach singing - many modern purists (not me) would blame Sutherland's vibrato and prefer more thin, boyish sounding voices, it is beautiful. The alto (Helen Watts) and tenor soloists are really good. The baritone Thomas Hemsley has intonation problems.
All three cantatas are based on famous Lutheran chorals, `Ein' feste Burg ist unser Gott' (BWV 80), "Sleepers, awake" (BWV 140) and "Jesu, Joy of Man's desiring" (BWV 147).
The filler in this compilation is Gönnenwein's recording of J.S.Bach's motet BWV 227.
The same Gönnenwein's recordings of BWV 140 and BWV 80 are also available in a different package, cf. Bach: Cantatas BWV 80, 140, 147; Jesu, meine Freude and Les Grandes Cantates. BWV 140 has also been reissued in a combination with BWV 106 and 78 (all with Gönnenwein)on EMI 25 21282. But unless you specially interested in Gönnenwein's performances of BWV 78 and 106, cf. J.s. Bach - Two Cantatas Bwv 78 Bwv 106 Wolfgang Gonnenwein Consortium Musicum, buy the reviewed item or its 'Gemini' replica.
