On Twin Infinitives, Royal Trux use their constantly mutating guitar lines and faint, twinkling, sustained keyboard notes to paint an acid-soaked vision of a nighttime cityscape’s dark underbelly. Streetlights sparkle through a veil of smoke, carrying a heavy drug-induced haze protruding from shadowy alleyways and underground clubs.

Jennifer Herrema is the star vocalist on Twin Infinitives, with her playful, childlike vocals endearing amidst the backing music’s trepidation. Both her and Neil Michael Hagerty sound fully entranced by their own music, locked off from the outside world while indirectly inviting us to join them and let yourself drift away in the primitively urgent noise. Even the album’s 15-minute highlight, “(Edge of the) Ape Oven,” never stops playing with you and thoroughly mesmerizes the entire way through, much like the rest of this 70-minute album. Twin Infinitives sounds like the sequel to EVOL, only going further down the rabbit hole—and discovering krautrock.
