U2 were feeling bold after the huge success of Achtung Baby, so during downtime from their groundbreaking Zoo TV tour, they headed back into the studio to push the experimentation even further on Zooropa. Originally intended to be a mere EP, they wrote so many great songs, they decided to release another album in the summer of 1993.
The debut single, "Numb," was weirder than anything on Achtung Baby. It's basically the Edge rapping in a monotone voice, and the video showed the guitarist facing the camera while U2 and various models rubbed stuff in his face and tied him up. The album didn't produce any enormous singles, but tracks like "Zooropa" and "Daddy's Gonna Pay for Your Crashed Car" have aged very well.
