The more concerts you experience, the more grows your confidence in being able to pick a good one. And this promised to be good, given the exceptional skill of the Academy of Ancient Music, and a team of soloists featuring Mary Bevan. However, and perhaps inevitably, I found myself relishing quite unexpected aspects of this evening of Bach, while not enjoying others to which I had long looked forward. Music written by Bach for the Collegium Musicum, and also for the first Sunday after Easter, was played with skill and flourish by this exceptional orchestra; sadly, the singing was not consistently good enough to match.
