I’m afraid that there is some confusion in the recent review (October 28th, ’25) by Nick Barnard, of a Bis recording of music by Schreker, Korngold and Krenek.
The overture for Schreker’s opera Die Gezeichneten is by no way shortened. This is the overture.

Mr Barnard confuses this with the Vorspiel zu einem Drama, also called Vorspiel zu einer großen Oper, which was composed as a standalone orchestral piece, although the music and its themes are similar (but the timings are not).

To add to this, Bis did not record the ”short” Overture on that other recording that Mr Barnard refers to. Bis-2212 includes the much longer Vorspiel.

May I also add that both recordings in question are excellent. I have them both.
