Fifteen years after the last official Rentals album, the 2014 album Lost in Alphaville is entering a marketplace where many potential fans were too young to notice when Matt Sharp’s old band Weezer were showing up regularly on MTV. This official third album is based on 10 songs that were cherrypicked from Sharp’s ambitious 2009 box set Songs About Time (which featured photos, films, and music) and then rerecorded with Black Keys drummer Patrick Carney, Ozma guitarist Ryen Slegr, and vocalists Jess Wolfe and Holly Laessig from the band Lucius, along with contributions from longtime foil Lauren Chipman and final mixes from Dave Sardy, who’s worked magic with LCD Soundsystem, Band of Horses, and Wolfmother. The unorthodox, long, and winding road from conception to completion yielded a completely fresh-sounding collection of ebullient pop songs. “Song of Remembering,” with Pixies’ Joey Santiago on lead guitar, is alone worth the price of admission. But surround it with songs of equal affection in “Thought of Sound” and “Seven Years,” and everything falls together to make a classic pop-rock album.
