An example from the past of a highly disturbing expressive music and a composer who was a revelation when i listened to him at 25 years old, almost in ectasy, is the great and unique Carlo Gesualdo...
My favorite interpretation by far is by the Quintet vocale Italiano...They convey the emotion before trying to be perfect and plastically beautiful...

Here the music is saturated "plaint" as saturated Schoenberg Gurrelider will be, the composer goal is to move the listener more than relax him... it is very difficult to interpret...because the singers must not sing for the music to be mere beautiful but emotionnally saturated by chord between harmony and dissinance...
For me Gesulado is not a secondary composer but as Monteverdi and on paqr with him a unique moment in musical history...
For sure i loved poetry all my life and Gesualdo is a supreme poet as Schubert will be in his own masterful way...

But la Venexiana ensemble impressed me too, they are more plastic in expression and very clear, less moving than Quintetto Italiano though... it is the same difference between Liszt Bolet and E. Ny. Liszt playing... I like the two pianists and the two vocal ensemble for different reasons...My favoritism dont erase the other interpretations good points ...
