On their new album Innocent Road, Caleb Klauder and Reeb Willms stake a claim as two of the finest traditional musicians in America. Their sound is a throwback to the heyday of rural American dance-hall music. And make no mistake: If they had been born in 1930, the two Portland musicians would be pop stars. But the duo performs classic country music in a modern world that often expects such sounds to be accompanied by kitsch and nostalgia. Nevertheless, they tackle the genre with refreshing verve and sing without an ironic wink.
