The Orchestra of Doom
From the "The Orchestra of Doom!" story of DC comic book House of Mystery #147 (December 1964).
Bear with us here. The Idol-Head of Diabolu was an inanimate nemesis of superhero Martian Manhunter. This mysterious object released an evil creature every full moon. One time it was the Orchestra of Doom, a band of weird, living, self-playing musical instruments, whose music made hearers turn violent.
