These are probably the three most famous U2 album covers; they represent the early, earnest days of the band.
How is it that they survived the October album? Most bands would have been utterly bankrupt and chased from the music business with a cover like that. Many have. And yet, they persevered. This was because they could play live. That is what people do not understand about the appeal of U2. The songs were good, but they became great live.
U2 hasn't had a decent album cover in twenty years.
