The incalculably influential Patsy Cline recorded only three LPs; Showcase remains the gold standard. Besides her mournful-but-infectious country-pop signature tunes (“Crazy,” “Walkin’ After Midnight,” “I Fall to Pieces”), Cline dips into both pop standards (Cole Porter’s “True Love”) and Western swing (Bob Wills’ “San Antonio Rose”) with the chops of a pop crooner and the soul of a country gal. Nashville legend Owen Bradley’s visionary production combines cutting-edge pop arrangement techniques with a heartland feel, for a sound that explores new territory without abandoning its roots.
