Query: A worth follow up to Achtung Baby

U2 wrote and recorded ACHTUNG BABY and then blew out onto the road with a massive show making fun of it all called ZooTV. It was literally the greatest show on Earth. After touring the U.S., Europe, and then another round of shows in the U.S., U2 had a few months of break time before bringing ZooTV around Europe, Australia, and Japan. Most bands would take a vacation. U2 locked themselves in the studio and came up with ZOOROPA. The album stands alone, and also works as a sequel to ACHTUNG BABY. Musically, it's a bold and experimental statement that won't appeal to all, but will excite many. Lyrically, it is a field day for Bono to finally get out emotions on the state of the world, touring, and life. Amazing that they were albe to make this in only a couple months. (Note: Zooropa is the second part to an unofficial trilogy that began with ACHTUNG BABY and would end with POP four years later.)
