If the shadow of Mozart still haunts Schubert’s Symphony No. 5, the Eighth (in no way “unfinished” in the eyes of its creator) already looks far into the future. Pablo Heras-Casado and the musicians of the Freiburg Baroque Orchestra lead us towards that Romantic style. Their flexible approach, keen and swift in the earlier symphony, making room for shadows and mystery in its successor, meets the challenge of bringing out the contrast between these “two Schuberts,” here more audible than ever.
