“I John” is Elvis gospel at its most propulsive. It’s sweaty—body music animated with the spirit of the Lord. “Baby, Let’s Play House” may be the Hillbilly Cat’s most lasciviously fun moment; but “I John” is surely the holiest—if by “holy” we mean gospel that omits the softly prayerful, hymnal touch. I like that. I like how the King reaches into the upper and lower registers of His voice, almost side by side. I like the reverb that sounds far less clunky and canned than it does on any of His other gospel records. I like that He sings excitedly, perhaps even desperately, of a man cornered by angels. I like that “I John” rocks.
