While studies have been conducted aiming to understand the science behind music, our inexplicable ability to tap into the emotions of another human being by way of arrangements of sonic frequencies still seems a bit like magic. LA's Death Valley Girls have always sought to wield that magic like ancient mystics, creating psychic bonds with willing ears through the medium of their fiery rock n' roll. On the surface, previous albums like Glow in the Dark and Darkness Rains were rowdy mash-ups of early American punk, sun-baked psych rock, and proto-metal fire-and-brimstone guitar worship, yet there was always an undercurrent of some kind of strange, celebratory communal ritual in their music. With their latest album Under the Spell of Joy, the band dives even deeper into that magical cosmic energy.
