“Derek Keeling as the Man in Black packs a deep, basso profundo rock voice that makes the floor tremble in "Riders in the Sky."

Canton Rep (Cleveland) by Dane Kane Oct. 17th 2011

“Derek Keeling doesn’t look just like Johnny Cash — he more closely resembles actor John Stamos, not a bad thing — but he has Cash’s deep and resonant vocal style down pat, along with the Man in Black’s lowdown swagger.”

Rochester Democrat and Chronicle by Marcia Morphy Oct. 26th 2011

“But let’s face it, The Man in Black always wins. And when Derek Keeling delivers the familiar introduction, “Hello, I’m Johnny Cash,” it was like channeling the bass-baritone icon.

“Derek Keeling's Johnny Cash, for instance, thrills the audience with his how-low-can-you-go vocal register.”

“Derek Keeling’s Johnny Cash is low-key and low-registered, but filled with smoldering depth.”

Journal Sentinel by Mike Fischer Nov. 16th 2011

“Derek Keeling matches the baritone-bass voice and dramatically convincing presentation of The Man in Black.”

“Derek Keeling's portrayal of Johnny Cash is remarkable. He resembles a young Cash, but more importantly his speaking and singing voices are eerily close to the star's. "I Walk the Line," "Folsom Prison Blues" and "Riders in the Sky" send a few shivers up the spine.”

Miami Herald (Miami) by Howard Cowen Dec. 30th 2011

“Keeling has by far the richest, most resonant voice and his booming Cash, on Tennessee Ernie Ford’s hit Sixteen Tons and Stan Jones’ (Ghost) Riders in the Sky, is top-shelf. “

Tampa Bay Times (Tampa) by John Fleming Jan. 5 2012

“Keeling's Cash is the most imitative performance, effectively capturing the man in black's deep voice and trademark guitar moves in such numbers as Folsom Prison Blues.”
