Edge, Bono and Adam in red

"We've learned a lot very late in the game. Technical stuff like song structure, een the basics of songwriting. But ultimately, all the technical stuff doesn't really diminish the huge emotional investment we need to continue. The essence of what we do has always been, and probably always will be, very daunting. It's always in the back of your mind that one day you might just draw a blank." - The Edge, 1992
