Onstage, the members of Stereolab might not be the most animated of performers -- 100-year-old oak trees have been known to move around more -- but they've always been great at beefing up their stylish sound in the concert setting, thickening it with layers of horns, guitars and added percussion to transform occasionally monotonous grooves into dynamic and mesmerizing jams. For this tour, at least, the band has retired many of the old hits in favor of Margerine material; a nod to Hansen's live irreplaceability and an acknowledgement that despite the recent tribulations, the show must indeed go on.
