One of the strongest roots of country music has always been gospel, so this collection of country stars delivering gospel tunes live at the Opry seems like a perfectly natural occurrence. From the Charlie Daniels Band's frenetic, Southern-rock-tinged take on "I'll Fly Away" to deep-voiced Nashville superstar Trace Adkins's agreeably loping, low-key version of "Wayfaring Stranger," HOW GREAT THOU ART lends just the right amount of twang and down-home flavor to a brace of enduring spiritual tunes.
