Back in 2000 when "At the Five Spot" was announced, I asked Ben Young (producer of the reissue) if "In Kansas City" was planned. He said "not currently". He said they decided the Five Spot name had more commercial potential than Kansas City. He did say it was unfortunate because there was "a bunch of extras" from the KC date.
I suggest starting with "Kenton Showcase". It is from the '53/54 era and has arrangements by Russo and Holman. This is a good example with some fine soloists. Then, if interested, move forwards and backwards - one step at a time.
What a bunch of silly boys. The real cookie is the trefoil (aka shortbread). They melt in the mouth with a nice butter/sugar flavor. At Thanksgiving we bought 6 boxes from our step-grand-daughter (is that a word?) and left them in Buffalo. Damn!
My apology to Mike Weil - my first edition of the book reads as Mike says. In my haste I was befuddled by a page turn.
I think John L's "on the other hand" interpretation is the most likely.
I used to have the original lp, but sent it to Japan for "big bucks" about 10 years ago. It is fine, but unless you have 5000 jazz cds, you don't "need" it.
