You didn’t come here to read about how tricky it can be to rate a musical work. But it isn’t always easy. Is it a five-star album? Maybe three? That depends on the taste of the listener.

For most acts, a hit single is the Holy Grail, though the as-yet-hitless Greencards are doing quite well, thank you. Fans of The Greencards appreciate the band’s great musicianship, emotive vocals and knack for transforming bluegrass-based fare into something spacious and musically challenging.

For them, this is likely at least a four-star album. Now, country radio probably won’t know what to do with this music, though the pleasant and hummable “Heart Fixer,” featuring Vince Gill, certainly has promise.

Overall, though, The Brick Album is built from subtle and artful stuff, sidestepping the obvious elements that lead to mainstream airplay. So, fans of today’s country radio might not be drawn in.

The moral here? Where ratings are concerned, the answer to the question “Will I like it?” isn’t always written in the stars.
