The Ascension Day cantatas were missed out of the Gardiner Cantata pilgrimage, probably because Ascension Day always falls on a Thursday, and it would have been an impossible job then to do the cantatas for the following Sunday. (BWV11 is often omitted from cantata surveys anyway, as it's subtitled "The Ascension Oratorio", and is seen as something different, like the Christmas Oratorio). However, thanks to the contributions of many donors, Gardiner has now done the business and recorded the four surviving Ascension Day cantatas at St. Giles Cripplegate, London, scene of some of the Cantata Pilgrimage recordings.
The Ascension Day cantatas are wonderful, joyful works, full of trumpets and drums. The best is BWV11 "Lobet Gott in seinem Reichen", but the others are also right up there, and Gardiner does them justice with great singing, great playing and, to my ears, perfectly judged tempos. A must-have for any Bach lover. Indeed, I would go further and say that, if you want only one CD of Bach cantatas, this must come perilously close to being it.
