The final words sung on the sixth album by WHY? are an apt place to begin: “Hold on, what’s going on?” There’s much familiar about Moh Lhean – mastermind Yoni Wolf’s sour-sweet croon, his deadpan poet’s drawl and ear for stunningly fluid psych-pop-folk-whatever arrangement. And yet a great deal has changed in the four years that’ve passed since 2012’s Mumps, Etc. – an LP that honed the band’s orchestral precision and self-deprecating swagger to a fine point. A low tone opens the album on “This Ole King” as acoustic pluck and upright bass form a Western bedrock beneath Wolf’s fragile voice. But as the song pushes on, the playing gets brighter and the vocal becomes a mantra-like hum inspired by Ali Farka Touré’s blues, before rolling into a second part rich with chiming keys and twisting harmony— Brian Wilson’s kaleidoscopic vision of pop.
