"His Double was countertenor John Holiday who displayed a fresh sound that melded with Mr. Hopkins seamlessly which was surely the intention."
"Commanding countertenor John Holiday gave a rapturous account of these florid gems...[and] a bravura account of four Henry Purcell songs in Morris’ 1985 'One Charming Night'... his ample, alluring voice sailed confidently through the hall."
"Exceptional [and] strong...even in its highest range"
"Arrestingly powerful, secure and dramatically high"
"A thing of astonishing beauty"
"Holiday is a force of nature, no doubt about it. His voice is supple, fierce, exceptionally beautiful, and has the power of the Radio City Music Hall organ. If there's a modern day Farinelli (the 18th century's star singer), he's it. Wonderfully dynamic, possessed of star wattage, somewhat celestial, he sings as if he had iron lungs."
"He has a gorgeous, expressive voice, that somehow balances sweetness and power, whether he's singing Baroque, gospel, American songbook or jazz."
"Holiday imbues everything he sings, regardless of genre, with his warm personal style and opulent voice, making classics from Handel to Thelonious Monk sparkle anew."
"One of the finest countertenors of his generation."
