Just as their band name recalls a time when the Royal Navy was the envy—or bane—of all the world, British Sea Power musically harken back to a world that rose and set with whatever next big thing was plastered on the front cover of the New Musical Express. On their fifth album, Valhalla Dancehall, this UK sextet recalls the romantic bombast and grandeur of both Britpop progenitors (Echo & The Bunnymen, Roxy Music) and standard-bearers (Pulp, Suede), as well as the pre-postmodern U2. British Sea Power might not have the truth on their side as Bono and friends once did, but they have chords and guitars to spare. Classic Education and North Elementary open —David Raposa
