Had a spin of Leftoverture yesterday, along with Point of Know Return. I prefer the latter. Kansas was one of those acts that I didn't dig in to when discovering classic rock in my teens. To that end, other bands left an indelible imprint on me in ways that Kansas (and others .. ELP, Alan Parsan's, Cooper, MSG etc....) never did/will. Great album, sure... but when I'm in a fix for 70s, I'll go to the Who, or Zeppelin, or Elton, or Boston, or .... insert a lot of others. I'm sure we're all the same way in that regard - some left a mark on our musical DNA; some didn't.
Kansas falls into the latter for me, despite being really great music. It's not that they don't click with me the way Tim/Bill state, it's just that I didn't give them a chance at the right time to be part of my 70s A List. They're on (my personal) B+List.
If that makes any sense.
