It was the whistle heard around the world. You heard Peter Bjorn and John's breakthrough single "Young Folks" on "Grey's Anatomy". You heard it on the in-house muzak system while waiting in line to order at McDonald's. You heard it every time your co-worker in a neighboring cubicle deigned to whistle while they worked. But while making their unwitting entry into the North American mainstream with 2006's Writer's Block, the Swedish trio of Peter Morén, Björn Yttling, and John Eriksson used their busy interview schedule to talk up far less populist inspirations: the minimalist post-punk of Young Marble Giants, the rhythmic jazz of the Ethiopiques series, and other Other Music-recommended curios.
