Weezer - those riff-loving, hook-hurling, inner-geek-embracing wags - has become the most reliable band in rock. Sixteen years in, the group continues to churn out crunchy anthems for misfits, nerds, and anyone with a soft spot for quirky, heavy power-pop. The songs are consistently vibrant, catchy, and well-built. Occasional stabs at earnestness notwithstanding, Weezer's lyrics probe frontman Rivers Cuomo's cosmic outsiderness in smart, sarcastic stanzas that come off like self-deprecating goofs but always leave you wondering: Is he laughing at us? Is he sadder than he seems? The chorus is righteous, so why should we even care?Not much has changed on the group's sixth album, a self-titled collection dubbed the Red Album. (Weezer's previous two self-titled projects were anointed the Blue Album and the Green Album.) In fact, one wishes that less had changed upon arriving at the disc's back end, which features token contributions from guitarist Brian Bell, bassist Scott Shriner, and drummer Patrick Wilson that sound like they were mistakenly grafted onto a Weezer album from some other, more forgettable, alt-rock band.Cuomo, newly mustachioed, has started playing around a bit with song structure, pushing beyond rock's usual verse-chorus-bridge pattern and into headier, linear territory. "The Greatest Man That Ever Lived (Variations on a Shaker Hymn)" is a sprawling folk-metal chorale that squashes wildly assorted references (Shakespeare, sex, and stardom) into epic musical settings (elegant harmonies, suite-like movements) and winds up sounding simply, fabulously faux.
