Chicago advertised that they would be playing their second album in it's entirety, and in my opinion did a great job performing it!!! Sadly many people enjoy only "hits".

I thought REO was ok, but I totally loved Chicago. The thing I've always loved about them is their horns. I thought they were phenomenal. They may have not performed all their hit songs, but what they did play was great.

Saw Chicago REO at The Pavillion. It was fantastic. New musicians in Chicago are great. particularly the new lead singer. For those of you who are complaining about them playing the entire second album. Wake up. I bought my tickets in March and knew at the time that was the plan. I’ve only seen Chicago about 6 times. By far the best.

REO was great as always. Kevin was right on with the vocals. Bruce and Dave sounded amazing. Plus Neal and Bryan were awesome as they always are. I've never been disappointed with an REO concert, and I've been to over 70. The same can't be said for Chicago. I saw them the last time they toured with REO (2014) and they were amazing. But last nights show was definitely not a good idea. Playing the entire Chicago 2 album, what were they thinking. Next time, give us a heads up before we buy the tickets (although I still would have gone to see REO). One last observation: I've never seen a venue shut down the general admission lawn seating and move everybody to reserved seating. Where were all the true reo fans. I know you're out there. I've seen you at other shows. REO, come back soon. Austin loves you, we always have and we always will.

Overall, a great concert. Not a huge REO fan but they were very good. I am a huge Chicago fan, have been for most of their 50+ years. If you really are a true Chicago fan, you would have enjoyed the music from the second album. True, not all of them were popular hits. However, they are still great songs and great music. The music and lyrics are moving, even in today's environment, which speaks loudly for the band and their music. My only complaint was with the sound system at the Allstate Arena. It was not good, which took away from the performances of both groups.

REO played a good solid set. I will admit that I am not a big fan. Chicago needs to be commended for going out on a limb and playing through all of Chicago I. That took courage. I was impressed with the musicality of the entire group. They, even with the replacements, continue to be polished musicians. Loved to hear this album played in entirety. My only regret, as always is that Terry Kath is missing. While the replacement musicians were fantastic they just aren't Terry. RIP. When is Peter returning? One of the best, of many Chicago concerts, I've attended.
