The rave-schooled Disco Biscuits have been among Phish’s heir apparents for a decade now, and with peers like STS9 opening for Jay-Z, maybe now is their time. Or not. At least their latest has big aesthetic balls: Heavy on beats and synthesizers, light on guitar wank, more about hooks than jams, it’s a departure from their noodle-dancing norm. But if they make nods to heroes like Pink Floyd, Radiohead — even OutKast — they definitely can’t write like them. The best song is ‘Big Wrecking Ball,’ a fat, familiar jam-rocker with a smokin’ Jon Gutwillig solo. How this stuff will mutate onstage — the band’s true home — is anyone’s guess.
