On Sleep and Wake-Up Songs, Okkervil River and principal songwriter Will Sheff take advantage of a break between albums to present a small collection of five more meditative songs that toss little boomerangs across the distance between what is and what could never be. They try on a loose-fitting felt suit of Tim Hardin-esque folk-pop, wade until soaked into a misty psychedelic duet, strap on an electric guitar for a lark, stack the overlapping refrains of Sheff and Minus Story's Jordan Geiger into a Phil Spector-esque ecstacy of sexual confusion, and finally strip things down to naked and initiate a straightforward love song
