There's something about the quiet of an early Saturday morning, when the streets are empty and the sky's full of pastels, that makes you feel like the only person on earth. KGNU's Honky Tonk Heroes, three hours of Americana and country-and-Western music, intensifies the disembodied vibe of the wee hours -- but in the most pleasant way imaginable. The show presents an amazing array of old-timey artists who used to be radio sweethearts -- Bob Wills, Ernest Tubb, Roy Acuff, Webb Pierce and Merle Travis -- plus a few wonderful nostalgic, transporting touches. You might even hear twenty minutes of Hank Williams playin' and pimpin' on a vintage recording of "The Old Flour Hour." Forget sleeping in: Honky Tonk Heroes is worth getting up for every time.
