The times were changing as our favorite Irish band U2 took on the mainstream world of the 1990s. This week, Carl Coleman and I chat about the ever-evolving music of "Achtung Baby," "Zooropa," and "POP" as well as why some were both hits and misses in our opinions. Plus, we talk about both the ZOO TV and PopMart tours from the craziness of their production, to the struggles of another.
