Brooklyn-based arch electro-rock hybridists Ratatat have continually pushed at the boundaries of guitar-based rock--incorporating elements of hip-hop, electro, and soundtrack music within their restlessly psychedelic productions. On the duo's third studio effort, the prosaically titled LP3, they venture even further afield from their previous guitar-driven efforts, combining baroque instrumentation and elements of world music with rugged hip-hop-influenced beats. Making full use of some decidedly vintage keyboards--a harpsichord, a mellotron, and a Wurlitzer--LP3 is marked by a cunning blend of artifice and naturalism, combining absurdly ornate keyboard lines with snatches of organic hand percussion. On the galloping "Falcon Jab," a reversed guitar weaves serpentine lines around a chicken-scratch guitar and disco strings--suggesting gypsy-funk as scored by Ennio Morricone. The spaghetti-western theme continues on "Mi Viejo," a dusty tabla-driven number punctuated by swirls of shimmering harpsichords.
