"It's easy to think that music made by relatively few people, with relatively familiar instruments, should fall under the canopy of "folk": uncluttered, transparent, linked to past traditions. Wildbirds and Peacedrums-- husband-and-wife Swedes Andreas Werliin and Mariam Wallentin-- compose most of their debut, Heartcore, with Werliin's compact drum work and Wallentin's orbital, precise vocals; there is an arc to their work that imbues it with the austerity and heartiness (no pun) of folk music. Despite its simple ingredients, Heartcore is neither native nor instinctual. "Primal" or "sparse" miss the point, too; Heartcore, instead, is cleverly orchestrated pop music preternaturally reliant on the skills of its performers: Both Werliin and Wallentin were music school dropouts, and their technically sound playing disguises the complexity and range of Heartcore's material."  - Pitchfork
