Chicago performed many of their classics which included their unique arrangements. Chicago is considered a popular rock band by many but their roots have always been and still are in jazz. Chicago still has a few of the original players in the band as you can see from the pictures above. If you are a Chicago fan you don't want to miss this concert tour when it gets to your area. I have to say that I did miss the voice of Peter Cetera in some of the older songs.
The level of musical talent from the musicians in both Chicago and The Doobie Brothers is outstanding; well worth the effort and cost of the ticket.
