Kaiku: The Sensual Sound of Cold Finland’s Hot Heart.

New York-based vocalists Jaana Kantola and Paula Jaakkola, above, record as Kaiku (“echo”), mostly singing in Finnish, the vowel-rich tongue of their icy, Northern European homeland, right. (Fully 25% of Finland rests within the Arctic Circle. In winter, at the country’s most boreal point, the cold season lasts seven months, void of sunrises for 51 days.)

But if your stereotype of Scandinavia is frigid weather; clean, efficient municipalities; socialized medicine; and people whose dispositions are as nippy as the climate, Kaiku’s new, self-produced album, Usva, may send you for a delightfully ecstatic loop.

Usva—the word means “mist,” evoking the hazy confusion of unrequited love—layers lush soundscapes that more evoke a warm Mediterranean sun than a distant, gray, Nordic light.

Artfully blending accordion, cello, piano, and bass on compositions like “Stay Your Hand,” “Illusions,” and the title track, Jaakola and Kantola, above, consider their ardent, “organic sound,” not some Culture Day demo but, “a mixture of rhythmic world music and traditional Finnish songs.” “Sure we come from Finland,” Kantola notes, “but our music is more like via Finland.”

Jaana Kantola and Paula Jaakkola are the guests today on my WBAI-NY / 99.5 FM radio show, NONFICTION, this afternoon, Friday, April 2, at 2 pm ET.
