Best known for his Mozart and Schubert interpretations, Daniel Behle turns to Bach for his latest album, a programme of arias for tenor and flute obbligato from the composer's sacred works. The concept is that the flute represents the otherworldly voice, angelic or divine, with which the soul, in moments of transcendence, holds its spiritual dialogue. There's no doubt about the beauty of Behle's singing or his remarkable ability to hint at subtle shifts of meaning with each repetition. Some of the numbers don't quite work out of context, however, and the sensuous grace with which he sings the opening aria of Ich Habe Genug leaves you wishing he had included the whole cantata, albeit at the expense of arias from the passions and the Benedictus from the B Minor Mass. Anne-Cathérine Heinzmann is the exquisite flautist, and there's fine orchestral playing from the Göppinger Kantorei under Klaus Rothaupt.
