Snakehole has returned, and on the Miami/Philadelphia noise rock duo’s new LP, Interludes of Insanity, KC Toimil and Autumn Casey up the clarity, volume, crunch, and sophistication in a major way. Recorded by the prolific and precise Ben Greenberg (Uniform, Mission Hubble) in Hudson, New York’s cavernous Waterfront Studios, Interludes of Insanity showcases the duo’s headway into layering and experimentation. The LP makes no qualms; it’s the main act, and it wedges itself firmly into the tradition of cohesive, almost narrative, albums.
