"You'll have to wait until almost the end of the first CD of this excellent four-CD set ... to hear music that you'd usually associate with the new ground plowed by Schoenberg. Most of the songs on the first CD could have been written by Hugo Wolf, or Schumann, Fauré or even Schubert! ... There is little clinical about these performances, though. They're all respectful and engaged, if a little formal. The quality of the singing is generally high ... Jens Peters Jakobsen's texts, which became those of the Gurrelieder, are of particular interest. They are sung particularly well by Diener and tenor Markus Schäfer ... This set has a lot going for it, then. Not only is it as complete as anything else available. It's been carefully conceived, imaginatively executed and well presented. There are songs here that are unavailable elsewhere".
