There’s no law that says bands with banjos, mandolins, fiddles and acoustic guitars have to sing about their Appalachian homes or even play country music at all. Bluegrass, the creation of a genius named Bill Monroe, was after all an amalgam of old-time country and the jazz that was America’s popular music in the 1940s. Canada’s Clumsy Lovers, best known for their live shows, had an original idea: For their major-label debut (after six indies) why not graft bassist Chris Jonat’s “Lola-era Kinks by way of Elvis Costello” songs onto an Americana foundation? The hybridization works well, and the unplugged racket results in a surprisingly thick mix. This stuff isn’t sleepy; it rocks, and even features snappy instrumental breaks borrowed from traditional tunes. So the operation was successful and the patient survived, but there’s still the question of Jonat’s sorta-derivative songs. The best of them—like “People I’ve been Meaning to Thank”—settle in nicely, but others are merely professional without hitting you in the solar plexus. Trevor Rogers’ voice gets a bit monotonous after a while, so it’s good to hear ace fiddle player Andrea Lewis taking the microphone once in a while. The Clumsy Lovers are worth watching, even when they fumble the romantic bits.
