Query: Hectically paced, poorly executed

Hermann Scherchen belongs with Jascha Horenstein in that quirky category of great conductors who recorded with such poor orchestras that it's often hard to listen to the results. Considering how truly terrible the Vienna Symphon(Pro Musica) was in the Westminster era, you have to tiptoe carefully indeed to avoid some real train wrecks. Even the Vienna Staatsoper orchestra, which is supposed to be composed of members of the Vienna Philharmonic, was veyr raggedy in those days. This is a breakneck Eroica performed without much technical finesse, yet among Scherhcen's Beethoven readings, it is typical in both respects.
