First few listens, I had Postcards from Texas clocked as median Miranda Lambert - nice but overly familiar, the sound a return to the polished sheen she settled into a few records back, the tempo mostly mid-, the melodies much like others she's offered before (tracks 2-4: "Dammit Randy" the type of ballad she does well but she's done it before (it plays as a less soaring, 15-years-on "Love Song"), "Looking Back on Luckenbach" the type of song that everyone's done before, "Santa Fe" having almost exactly the same verse as Pistol Annies' "Best Years of My Life" but far less dynamic).
It gets better with repeated plays though - she's such a strong songwriter and singer that the songs come through more in their own right even when their packaging isn't at first particularly distinctive. And even though they're not all-timers amidst her excellent back catalogue, numbers like "Armadillo", "Dammit Randy", "January Heart", "Run" and "Alimony" have more than a sprinkling of what it is that's made Lambert such a stand-out across her career as a whole.
