I simply love this aria, and Janet Baker, to me, has the perfect tone of voice for this beautiful transcription from Bach's cantata.
"British legend Dame Janet Baker sings with emotional depth, warmth and grace one of my most beloved Bach arias, this from the Cantata BWV 170. 'Vergnügte Ruh', beliebte Seelenlust' / 'Contented rest, beloved soul's desire' Sir Neville Marriner Academy of St Martin-in-the-Fields Recorded in Decca Studio No."
