Over the clatter of piano and strum of an electric guitar that opens his fourth studio album, Josh Ritter leaps into rapid-fire lyrics that reference Joan of Arc, Calamity Jane and Florence Nightingale, all of whom seem to be struck together in the belly of a whale. As the follow-up to last year's critically acclaimed album The Animal Years, The Historical Conquests Of Josh Ritter is his most adventurous, fresh, and freewheeling work to date.

You're presently reading about what may be the best album of 2007, hands down, by the most under-accorded American musical genius. Real murmurs, believable ones, came with Josh Ritter's 2006 album, Animal Year, suggesting that the Idahoan is today's Bruce Springsteen, today's Bob Dylan. He's never sounded more the part than on Historical Conquests, the follow-up to Animal. Ritter's tripping over his syllables and allusions on the opener, "To the Dogs or Whoever," dropping biblical and historical images like a fresh-faced Dylan. Except here, Ritter throws in an organ-fueled, ride-cymbal-crashing, drum-hefty clatter. It's majestic, and it's only the first three minutes. Recorded between stints on a never-ending tour, Historical reflects Ritter on the road, quick witted, a master of phraseology and of imagery. Horns show up as color, giving Ritter a soulful vibe on "Right Moves," a raucous funkiness on "Rumors," and a doleful cloudiness on "The Temptation of Adam." More than anything, Ritter here lays claim to absolute singularity--yes, colored by Dylan and Bruce but simultaneously enlivened by something magical and simple and gorgeous. --Andrew Bartlett
