If Jay-Z is the King of Summer Jam, Busta Rhymes has to be the Prime Minister. He's rocked that stage many times, but in 2003 he took things to another level. Not only did the usually friendly Bussa Buss shock fans by joining 50 and Eminem in their Ja Rule roasting, but the Dungeon Dragon also played host to a slew of special guests including Diddy—flanked by Mr. Bentley—Don Magic Juan for “Pass the Courvoisier,” Mr. Sean-a-Paul for “Make It Clap (Remix),” a topless Bonecrusher for “Never Scared,” and none other than Mariah Carey for “I Know What You Want.” Talk about a powerful impact!
