Quasthoff’s reputation has increased with each new disc‚ so it is a good idea of RCA’s to issue this composite picture of his achievements to date. We are here reminded that the eminent bass­baritone has just about every virtue called for in practically all the repertory included here. His voice is faultless in tonal production and technical assurance: he always sings with thought for the text; word and note become as one. These assets are controlled by a sharp‚ intelligent mind and an emotional impulse that makes every reading a sustenance for ear and mind. The Schubert group – four dramatic songs‚ one reflective – are delivered with a marked emphasis on firm tone‚ a refined legato and acute use of text. His Schumann is hardly less successful. The two airs from Bach’s St John Passion have the breadth of line and sonorous voice that make them near­ideal. In Mozart‚ his imposing account of Count Almaviva’s outburst contrasts nicely with his suave Giovanni‚ but his Leporello is rather too well­behaved. The traversal of Sarastro’s second aria is the very epitome of wise authority and most beautiful to hear. He plays Papageno pretty straight‚ and then – in the only new item here – he’s joined by Caballé‚ of all singers‚ for the duet with Papagena‚ a real collector’s piece‚ the then 65­year­old diva just about keeping up with her partner. Finally comes the closing scene of Fidelio with Quasthoff‚ as I wrote when the set came out‚ as noble and warm a Don Fernando as one could wish. Sir Colin Davis is at his best in this extract from what overall is an uneven set. Elsewhere in the present compilation the piano playing and conducting are all worthy of this artist’s profoundly satisfying work.
