Based on Sheb Wooley’s campy “Purple People Eater” and Katy Perry’s headache-inducing “ET,” it’s difficult to imagine that someone could pen a quality song about extraterrestrials, but Grass Widow’s “Goldilocks Zone” is proof that it’s possible. The lead single from the three-piece outfit’s upcoming album Internal Logic ponders the possibility of outside lifeforms in the NASA-delineated “Habitable Zone,” whose nickname provides the title for their track. “Without seeing the little green guys, our imagination can run wild,” vocalist Hannah Lew says. “This state of boundless imagination is a blissful place of wonderment and a celebration of the unknown, rather than a fear of it. I think the song describes that sonically.”  Indeed, “Goldilocks Zone”’s angular noise, dizzying guitar chords, and eerie harmonies give the feeling of being tugged through a series of sonic realms. The San Francisco group’s dissonance is so effective that you might find yourself frantically sifting through your browsers, looking to close other sources of audio. But Lew offers another another explanation for their dislodged sound, “We are three individuals and I think that multiplicity is represented within our music.”

Internal Logic is due out May 22 on the band’s own HLR label.
