This is a surprise: Mahler's "Resurrection" Symphony, in a renowned 1963 performance conducted by Otto Klemperer. (This symphony was effectively Klemperer's calling card.) Classical reviewer David Hurwitz called the 1998 CD remaster on EMI Classics "among the finest recordings that the piece has ever received." This big-ambience Atmos upmix gives it even more clarity, dynamics, and immediacy. Whatever technology the Warner Classics engineers are using, they're using it right.
