A lot has happened during Fleet Foxes’ six year hiatus — just ask former drummer Josh Tillman, who split from the band shortly after the band’s second LP, Helplessness Blues, with time to release three records of his signature brand of misanthropic folk rock before the remaining Fleet Foxes produced one. Not to say the other members of the band were lazy on their time off — lead singer Robin Pecknold was pursuing academia at Columbia University and guitarist Skyler Skjelset spent time touring with dream pop duo Beach House. Well finally, the Fleet Foxes long anticipated third album, Crack-Up, has come, and while this new LP certainly reflects a band that has changed since their last record, everything that defined the Fleet Foxes on their previous two albums — nonlinear song structure, reverb-soaked vocal harmonies, layered instrumentation — is all very much there. This album still certainly evokes the rustic respite of a backcountry sojourn, but it is also processed enough to remind you of the smartphone you rely on to take pictures when the landscape most precisely captivates you. Crack-Up serves as loosely defined concept album that explores the theme that “no man is an island” to varying degrees.
