"There aren't many venues that make a difference, but the Garden does," says top agent Dennis Arfa, who reps Billy Joel and Metallica. With its prime Manhattan location and a surprisingly intimate vibe, it's no wonder Bruce Springsteen has played here 44 times since 1978. Other stars who have touched down here include Led Zeppelin, David Bowie, Elton John, James Brown, Madonna and Swedish House Mafia, among many – basically everyone who's anyone. "The public pays to go there," adds Arfa. "I tell my artists: 'MSG may be more expensive, but in return you get back more tickets at a higher price.'"
Fun fact: The current building, in midtown Manhattan, is the fourth to be called "Madison Square Garden." It opened in 1968 with an event starring Bob Hope and Bing Crosby.
