End of 1989 you had indeed fear that Bono and his colleagues were burned and this band was dissolved. Instead, they brought with "Achtung Baby" released their best album well. "The Joshua Tree" and "Rattle and Hum" are absolute milestones deieser brilliant band and are rightly to their best albums, but "Achtung Baby" sounds different from the other albums still mad state. The songs are catchy and to melt away, rocking, energetic, deep and very diverse. It is in my opinion one of the best rock albums of all time. Necessarily buy !!!
