The new Karen O/Danger Mouse collaboration takes plenty of interesting directions in it’s duration, but hearing KO on something like “Nox Lumina” is most thrilling of all. It forms a rich bookend for the album with the ambitious opening single “Lux Prima”, it’s counterpart.

Over an eccentric guitar+synth+string blend, she repeats these cryptic lines over and over:

Somewhere in my room

Sometimes I don’t lock the door

Every time I close my eyes

Someone else’s paradise

Turns me into someone new

She sounds calm but unsteady or even possessed as the melody suggests a lurking danger. Suddenly her voice distorts and slows down along the lines of her wordless wailing in “Lux Prima”. As if it wasn’t fit for a surrealist short film already, “Nox Lumina” ends the album with a reprise of “Prima”’s orchestral flourish like the credits are rolling.
