Staier + Erard vs. Schumann (my first HIP Schumann recording?)
Schmidt vs. Rajter. Hat-tip, Sarge. There is another edition of the same Rajter recordings with this ASIN: B000001XPA
That one can be bought from Amazon France MP for ~18€ before shipping, FYI. The other options I saw tended to be used and/or expensive.
What is Mehtaphysics? I got this for the Schmidt #4, though it seems the Mahler is supposed to be killer, too. I saw another slightly older disc with this Schmidt coupled with Schoenberg CHAMBER SYMPH #1, which piece I really like; but I think I can get that Schoenberg on another Decca all-Schoenberg release.
Ce Diabolic Chant! Phil Pickett and the Goth-Industrial Ensemble of London.
Fournier vs. Bruch, Bloch, Lalo, Saint-Saens: I don't know any of these composers well, so this will be a treat. Not sure I've heard any of these pieces before.
