The Fiery Furnaces, consisting of brother/sister duo Matthew and Eleanor Freidberger, spent most of 00's proving just how ambitious, inventive and varied pop music could be. The two started attracting attention after the release of their debut, Gallowsbird's Bark, but that was primitive, at least relative to what the duo would produce later. 2004's sophomore release, "Blueberry Boat" showed just how ambitious they were in terms of song structure and lyricism - the album played out like a series of schizophrenic operas, Eleanor's pinpoint enunciation ringing clear over Matthew's oddball synthesizer melodies and constant changes in rhythm, tempo and style that made their music seem so irreverent and unique, and as an album, really showcased how talented the two were, and lay the foundation for their later work - including this, which in my opinion, is truly their magnum opus.
