German baritone Benjamin Appl confronts Schubert, Brahms, Wolf, and more with a hearty embrace in this collection. Appl’s rich baritone dominates Schubert’s “Nachtstück,” conjuring its flawless melodies and unrestricted temporality with lucid clarity. Britten’s reading of “Greensleeves” is a perceptive one, with a wealth of mystery and shimmer.
