Perhaps the only thing more self-indulgent than issuing a double album is planning a surprise party for yourself and then feigning astonishment when your guests emerge. Many such releases have been ostentatious excursions of masturbatory significance, while others (Bitches Brew, London Calling, Sign of the Times, Life After Death) have been warranted, even momentous, justified in that they captured the respective musicians at their creative apex. Granted, the Foo Fighters can hardly be seen as timeless trailblazers on par with any of those artists. Nonetheless, the act's latest certainly leans in that direction. Honor contains some of the band's sharpest material since The Colour and the Shape, which also threatens to undermine it: Ultimately, the former sounds like an extended version of the latter. Honor's first disc is brimming with Dave Grohl's trademark adrenalized anthems, while the second summons its inner Cat Stevens. Even so, the package's list price is commensurate with that of a single offering -- and that in itself is worthy of honor.
