There's a bright, bubbly friskiness to every Vampire Weekend song, but it's always reined in by a tidy, timeless pop hook—and some deceptively intricate instrumentation. While "Ottoman" plays with harpsichord-infused Afropop, the marimba of "Horchata" plinks and plops with the delicacy of a tropical rainstorm. Piano ballads "Obvious Bicycle" and "Young Lion" show off some stunning harmonies.
