Donny had power, smoothness and perfect tone and pitch. Don't get me
wrong Luther can sang and had the lil smoothness for the ladies on lock.
But if you listen to Donny's entire catalog and really understand what
he was doing vocally, there's no way Luther can touch that man's vocals.
Donny is one of the most naturally and technically gifted singers to ever
do it. Luther simply had the ladies crooner gimmick. Donny never had
ONE piece of smoke or mirror with his shit.
