The same two pairs of twins applied their approach to Black Sabbath’s “Paranoid.” As a song by one of heavy metal’s forerunners, it begins with an even heavier character. The Volfgang Twins retain that force through their drumming, but the Harp Twins introduce an unexpectedly delicate element. The contrast produces another extensive reworking rather than a close reproduction.

These recordings illustrate the choice facing musicians who cover existing material: remain as faithful as possible or establish a separate identity for the new rendition. The Harp Twins and Volfgang Twins chose the latter course. Their versions honor two widely admired songs while allowing the collaborators’ own ideas to determine how the music is presented.

By combining the Harp Twins’ rock and Celtic background with the Volfgang Twins’ Nordic inspiration, the musicians gave “Paint It Black” a fresh, mystical form that attracted millions of views. The cover reflects their creative treatment of the established hit, while “Paranoid” offers another example of how the collaboration reshaped heavier source material into something distinct. Their other projects provide further opportunities to explore the work created by the two duos.
