A sold-out Nectar was packed like a sardine can with a well-groomed all-ages crowd yesterday by 6:15 for a happy hour (only sans booze downstairs) show by the polarizing local act Barcelona, whose three members went to school across the canal from the club at SPU. In this week’s issue, I launched a critical defense of the band, whose music and members I personally like a great deal. But seeing them live again gave some credence to their detractors; the lush, Colplay-esque trio walks a fine line between passionate and douchey, and their crowd does too. They can’t help the crowd, but they could do without the mimicry of Chris Martin’s spastic stage gyrations and the faux British accents. The band can stay true to itself and ditch those affectations rather easily. Or so one hopes.That said, there’s no denying Barcelona’s talent. They are an extremely polished outfit with a lush, dreamy sound, sure to be in heavy rotation on both the radio and the CW in the very near future (their major label debut drops at the end of the month). Their decision to have a three-piece string section accompany them onstage last night at Nectar proved particularly shrewd; when you’ve got an orchestral sound, why fight it?To ignore Barcelona’s success and the reasons for it is to thumb one’s nose at a significant faction of Seattle’s music-consuming community. They may not boast the most Lester Bangsian knowledge of rock history, or immersed themselves in Joy Division and MC5 bootlegs, but nobody’s duping them into falling all over this band. Yet despite the fact that I still like them, last night helped me better understand why others don’t.
