From Gustav Ophüls in his Memories of Johannes Brahms: "... It was more an intensified recitation of Biblical text in tones, which he gave us in his hoarse voice; and what we heard was entirely different than an art song. Since then, no singer, not even Meschaert himself, has been able to awaken the same mighty impression in me, which the improvised rendition of these songs by their creator made on me at that time. It was actually no different than if the prophet himself had spoken to us ... The third song, 'O death, how bitter thou art,' plainly gripped him so strongly during its delivery, that during the quiet close, 'O death, acceptable is thy sentence,' great tears rolled down his cheeks, and he virtually breathed these last words of the text, with a voice nearly choked with tears. I shall just never forget the moving impression of this song."
