Ich habe genug is a timeless, transcendental masterpiece: a profound expression of Christian faith at the very end of life. It demands artistry of a special order, and Iestyn Davies now joins the likes of Dietrich Fischer-Dieskau and Lorraine Hunt Lieberson in the work’s distinguished discography. The couplings are equally ravishing performances of two other great solo cantatas, while the two orchestral sinfonias which complete the album will prove refreshingly familiar.
