“I’m lost in the sea of sweet design,” Yeah Yeah Yeahs’ Karen O coos reverently and breathily on “Ministry,” a gauzy soundscape from Lux Prima, her recent album with Danger Mouse. “So day by day, I’ll turn my dreams into a ministry, a ministry, a ministry of her love.” Throughout the record, producer/multi-instrumentalist Danger Mouse designs a candied sea of watery sounds that blend with Karen O’s whispery vocals. Tracks range from the low-key disco of “Turn the Light” and the mutated ’60s garage-pop of “Woman” to the softly spacey electronic shimmers of the nine-minute title track. The duo reportedly decided to collaborate more than a decade ago but didn’t start recording until two years ago. These two weekend shows at the Ace Hotel will apparently be their only live performances of the work.
