Leading conductors in the orchestral world — including Riccardo Muti and Esa-Pekka Salonen — have personally approved spatial audio mixes of their recent recordings, which have been released on Apple Music and its stand-alone classical streaming app. And, as with other genres, Apple has gathered playlists of spatialized remixes.
The regular players in classical music’s immersive cohort have meanwhile continued to ply their trade: Members of SWR Experimentalstudio came to the Time Spans Festival in New York this month, bringing surround-sound works by the Italian modernist Luigi Nono. And the American composer-saxophonist Anthony Braxton brought a new surround-sound concept, “Thunder Music,” to the Darmstadt Summer Course in Germany.
Those live performances were terrific. It’s a different story on recordings: After listening to a variety of Dolby Atmos mixes recently, I sensed that classical music’s more mainstream slate of spatial offerings remains a work in progress.
Somewhere in between was the Sonic Sphere, a realization of a spatial audio concept by Stockhausen, at the Shed in New York this summer. Its 124-speaker setup encircled about 200 listeners at a time. In early July, I heard a new mix of Steve Reich’s “Music for 18 Musicians” that suffered from muddy bass frequencies. This, unfortunately, also robbed the work of its chiseled, Minimalist grace; instead of following the bass clarinet lines, you just guessed that they were there. A sense of drama had been frittered away.
Similarly, some selections you can find in Apple Music’s “Classical in Spatial Audio” playlists seem poorly selected for the format. A recording of a profound solo work like Bach’s “The Well-Tempered Clavier” isn’t exactly crying out for the spatial treatment. But when it receives one — as in an otherwise pleasant recording by Fazil Say — it merely sounds like it’s had its reverb levels jacked to the sky. It’s more distracting than moving. Such extraneous mixes are also a poor advertisement for what Dolby Atmos can provide when applied to the right repertoire.
