Five songs by Chicago that don't sound like Chicago

Chicago was a great band and most people don't know how diverse and interesting they really were. There are way more than this, with their classical and progressive pieces on II, III, VII and elsewhere, but this is the best I can do at 5AM.
  1. I Don't Want Your Money (Chicago III)
  2. Flight 602 (Chicago III)
  3. Skinny Boy (Chicago VII)
  4. South California Purples (Chicago Transit Authority)
  5. What Else Can I Say (Chicago III)
