By the way, this was a damn good concert.
REO opened with about a dozen songs. In between, Kevin Cronin would talk to the audience like we were just sitting in his living room having drinks. One particularly powerful story he told was about 9/11. The band was in Los Angeles at the time, with their next concert scheduled in Salt Lake City 3 days later. They made the drive up, not knowing if they would be ready to play or if there would even be much of an audience to play to. But when they got to the venue, there were 10,000 screaming fans waiting for them, and they said it was one of the most memorable shows that ever played. It was at that point that they felt like things were finally going to be okay again.
Chicago's set was even more impressive. They started by playing their amazing second album in its entirety. Even though it was out of order, they ended that part of the set with an absolutely scorching rendition of 25 or 6 to 4. It was probably a big shock to some of their johnny-come-lately fans to discover the Chicago was, in fact, a ROCK band back in the day.
The second half of their set was dedicated to a bunch of their hits, with only two from the 80s ballad era: "Hard To Say I'm Sorry" (complete with the "Get Away" outro) and "You're The Inspiration". There were a lot of great songs I hadn't heard in a long time.
All in all, a fantastic night.
