Have Brighton's promising Britpoppers been taking Ritalin? British Sea Power's debut, 2003's The Decline of British Sea Power, was a manic mix of the Pixies, Pavement, and Proust, but alas, that feral energy has evaporated. In its place are well-bred rock numbers that chug dutifully forward, running on mannered riffs and indifferent vocals. Open Season does have its moments the James-like transcendence of ''Please Stand Up'' and slow-burn spookiness of ''Be Gone'' both raise gooseflesh but the only real surprise is its wan predictability.
