Nashville, Tenn. (TN Tribune)-Darryl Frierson, one-half of the twin duo the Joy Boyz, passed away. If family groups are ubiquitous in gospel music, brother groups are less common, singing twin brothers even less so, and singing twin brothers who stand less than 4 feet tall apiece, almost unheard of. But that’s what makes the Joy Boyz distinctive. Diminutive in size though not in sound-physically, they are a 180 degree difference from the portly Edgar and Edward O’Neal of the O’Neal Twins-the charismatic Donnie and Darryl Frierson make a joyful noise.
