I will admit it, Kris Kross was the very first CD I ever owned.  Do you remember them?  Chris "Mac Daddy" Kelly and Chris "Daddy Mac" Smith sang "Jump" and wore their clothes backwards? It's been over 20 years but they are ready to get back into the spotlight.  They've just announced they are reuniting for a 20th anniversary all-star concert honoring So So Def Recordings in Atlanta next month.
