Christine Schäfer's bright, silvery soprano is a perfect vehicle for these solo cantatas. The adventurous Musica Antiqua Kn supports her in lively readings, full of spirit and animation. Schäfer sails through the technical demands with ease, but she also brings a welcome warmth and sensitivity to the texts. Some of the movements are taken at a clip that may surprise, but the performers bring it off with aplomb. The familiar Cantata No. 51 actually isn't a wedding cantata, but its joyous spirit fits the mood, so it's welcome all the same, especially in a performance of such agility and precision. I could do without the cutesy packaging (the disc's sleeve has a heart-shaped centrepiece)--but who cares when everything else is so good?--Dan Davis
