NPR has an interview with lead Foo Fighter Dave Grohl, Dave Grohl: How To Make An Arena Feel Like A Punk Club. He cites Freddie Mercury, Paul McCartney and Bruce Springsteen as role models for how to bring intimacy to large-scale performance. Take a look at the Media Center and decide for yourself with these examples:
Queen Rock Montreal and Live Aid, DVD 3279-3280
Paul McCartney: Good Evening New York City, DVD 3889
Bruce Springsteen & the E Street Band: Live in New York City, DVD 515-516
While I'm not the U2 fan that I was once, I still continue to be amazed by Bono's ability to hold a huge audience in the palm of his hand. See for yourself and make up your own mind.
