Generally speaking, when a band hopscotches its way through genres on one disc it results in a compartmentalized affair: Certain songs feed certain moods but rarely taste good all in one sitting.
Former indie darlings Rilo Kiley pull off one of the best recent exceptions to that conventional wisdom with their instantly infectious fourth release, "Under the Blacklight."
The California-based quartet, now recording for Warner Bros., mixes and matches freely, from alt-country and disco to ethereal piano pop and spiky funk. And yet they tie what sounds like a mess on paper into a delightfully tidy and unified whole. Even though the 11 tracks differ in style, emitting flashes of everyone from George Harrison ("Silver Lining") to Janis Joplin ("15") to the Yeah Yeah Yeahs ("Moneymaker"), they have three important elements in common.
