Sibley has the overture, but it seems from the first page of score (with stage instructions, instructions for 4 theatre trumpets, etc.) that this is not an independent concert overture but the overture to incidental music. Also fairly clear from score that the text is used, in German. Segments of the incidental music -probably- use voices and chorus (-not definite there?) but in German if so.
This Programme (Google books) comparing various settings, etc. of Macbeth, provides further information.
