Unlike In Search Of..., originally made primarily on N.E.R.D.'s various machines and then reconfigured with assistance from funk-rock band Spymob, Fly or Die is kept almost entirely in-house. The ridiculous cover, along with first single "She Wants to Move" -- and its accompanying video, including a literal translation of the line "Her ass is a spaceship I want to ride" -- thankfully provide little indication of the album's true makeup. And the moments where the Star Trak hand sign gets flipped to a set of devil horns are mercifully fleeting, though "Backseat Love" is undoubtedly problematic -- it plays Dumberer to "She Wants to Move"'s Dumber. ("Lapdance" was Dumb.) The rest of the album isn't just noteworthy for subject matter that skips through child-parent relationship sketches, ecological reveries, and protest songs; the bright, bold Neptunes glaze that normally coats their chart-aimed singles of all stripes is applied to material that will leave many people baffled. The album sees N.E.R.D. rummaging through parts of their record collection that don't normally bubble to the surface in their production work.
