For their seventh album in 10 years, The Walkmen keep refining their strangely catchy brand of moody indie rock. Heaven is a bit slower than its predecessors, but Hamilton Leithauser’s wonderfully drawn-out and affected voice is there at the forefront, floating atop a choppy sea of strummed guitars and thick bass lines. Thanks to the renowned Seattle-based producer Phil Ek (his generation’s answer to Joe Boyd), the electric sparks of a great live show combine with the layered intricacies of a labored-over studio album. “Heaven” is a detuned jangle-romp that flirts briefly with being an anthem before going home and crawling into bed. “Line by Line” is an unabashed lullaby. “No One Ever Sleeps” is the soundtrack to a waking dream. And “Heartbreaker” is a suave little foray into the post-Velvets night. When Leithauser intones “We’ll never leave/The world is ours” on “We Can’t Be Beat,” you pray he’s even a little bit right.
