ASK JOSH HERMAN IF HE CAN remember the moment he realized he was a success, and the burly 26-year-old doesn’t hesitate. It was Feb 21 1996 the night he attended his client Snoop Doggy Dogg’s party at Monty’s restaurant in Los Angeles, a celebration of Snoop’s acquittal on murder charges. Handed a bottle of Cristal champagne as he entered the rooftop eatery, the white boy straight outta middle-class West L.A. strolled over to chat with rapper Tupac Shakur and producer Suge Knight.
