Naxos released some digital only releases with boldly tasty titles like Bleeding Chunks of Wagner and Music for the Zombie Apocalypse. Read more about their newest adventure on this detailed LA Time article.
The playlist Naxos compiled for Zombie Apocalypse feature ten more tracks than the digital compilation, It is a weird but timely playlist that demonstrates the great range of Naxos's catalog, which offers a great sampling of music people both know (Fauré Requiem, Schnittke quartet etc, but presented in a new context) and don't know (beware, you will never forget the sound of a Gloria Coates symphony or Michael Gordon's Timber once you hear it, not just on Halloween).
Here's the Spotify playlist from Naxos: Music for the Zombie Apocalypse (30 tracks, total time: 2 hours). Read more about the compilation/playlist here on ZombieHub.
