It's kind of absurd that the Fiery Furnaces, a brother-and-sister duo with only two albums to their name, are already releasing a collection of singles, B-sides and other ephemera. But in this pair's warped world, where eight-minute songs pile as many disparate styles together as clothes at the local Goodwill, EP is a perfectly logical endeavor. In fact, this mini-album, still a hefty 10 songs long, is sort of a Cliffs Notes version of the band's sound, one that compresses its lengthy opuses into bite-sized songs without losing their childlike sense of adventure. Singles "Tropical Ice-Land" and "Single Again" fizz with a catchy focus but veer from whimsical synth collages to sputters of toy percussion; B-sides "Evergreen" and "Here Comes the Summer" add classic rock-guitar pomp and electropop stomp, respectively. The rest of EP's songs suffer from attention-deficit disorder when it comes to genre; "Duffer St. George," for example, is a mash-up of mad-scientist piano, grimy garage rock, U.K. psychedelic breeziness and pastoral flute flutters. But like a toddler's finger painting or the works of Jackson Pollock, EP is an entirely cohesive--and thoroughly enjoyable--mess.
