Radiohead - In Rainbows

Today was like the day after a big game. I have talked to more people about this then any album event in a long time. I am impressed how this has really opened the dialog and has generated some really great conversations about the future of the music business. The real question now is how does a new band get to be as big as Radiohead without the initial marketing that the labels provided? Not that I go to many arena shows anymore but here is a list of bands rolling through Seattle's Key Arena; Ozzy, Billy Joel & Van Halen. Who is going to play the arena's when the 70s, 80s & 90s bands finally fade away?
