"I have nothing but respect for U2 because they have managed to stay together as a band for decades. They have stayed viable at a very high level through the many changes in the industry over the years. They have given back so much to people in need, making a real difference in the lives of millions of people around the globe. They are truly a class act. Bravo!"

Bob Lefsetz, industry commentator/author of the "Lefsetz Letter" blog

"They matter financially. And to those in their forties who remember 'The Joshua Tree.'

"They're meaningless in terms of new music. If only they'd realize this, and start to record and release new music that's not overmanaged and overmanipulated to try and be successful, but is recorded for the pure joy of it."

John Baldwin Gourley, singer/guitarist, Portugal. The Man

"U2 will matter forever, that is not up for debate. I just can't imagine charging your fans, who have made you, that much for a concert or a T-shirt, but maybe I have no perspective of the size of things"

Kasim Sulton, bassist/singer, Utopia, session and touring pro

"Very few bands/musicians have the capacity to remain popular and contemporary after 25 years together. Much like a roman candle, there might be four or five truly good records before the magic sputters and the artists find themselves held hostage to their initial success, playing the same old songs because that's all the audience really wants. U2 is one of the only bands that consistently tops the last record, the last tour, and continues to remain one of--if not the only--bands that can release an album and have it mean more than the previous one. Consistently. Case in point: The Rolling Stones, Elton John, Paul McCartney, Billy Joel, Aerosmith and most other artists in that stratosphere of success can still sell out tour after tour, yet nothing they've released in the last 15 years compares to their early material. U2 still matters."
