Fans of Ratatat’s insanely catchy track “Seventeen Years” will be surprised to hear the first song on its second LP, “Classics.” “Montanita” opens the album with what sounds like the music from a spaghetti Western filtered through Ratatat’s electrified instrumental blend of thumping beats and soaring melodies. But skip one track forward to “Lex” and you’re back where you expect to be with this band: out of the desert and onto the dancefloor. There are sounds on this album that are new for Ratatat, like the roller-rink disco with growling feral sound effects on “Wildcat,” but the duo gives us a lot more of what it did best on its self-titled debut. That’s anything but a criticism; its sound manages to develop without losing the characteristics that made the group great in the first place. Always experimenting without losing what makes its sound so likeable, as their breakthrough single puts it, Ratatat just kicks it from the head, you know what I’m sayin? (Seth Mayer)
