en Cuevana 3. Deutsche Grammophon celebrates Nikolaus Harnoncourt's 80th birthday with this 2-DVD release of rare, vintage, period Bach performances for the first time. Never released on DVD and, to the dismay of fans, long unavailable--these glorious Bach pieces are conducted by period instrument pioneer, Nikolaus Harnoncourt, as only he can. Harnoncourt, a notable cellist, performs in two concertos and on gamba in one. Harnoncourt warns, "If we lose contact with the great works of Bach, we lose our contact with humanity." Vocalists Janet Perry, Robert Holl, and Peter Schreier sing with distinction in the Coffee Cantata. The Surround Sound makes clear that they revel in the acoustics of the visually magnificent Baroque library of Wiblingen Monastery.
