I never pass up a Jim Flora cover. Some are better than others, but it's hard for me to rank them.
To Larry's point: I did buy the album for the cover, and spun it once, and didn't care for it. I am not a fan of Andre Previn's "jazz," at least what I've heard.
And with Shorty Rogers, I feel like I started with the best and could never find anything as good afterward. I became aware of him through a CD called "Short Stops," which collected two of his early 10" albums and the Wild One EP. I then started picking up all of the LPs I could find, but none of them ever struck me like the music on that CD. Is it because those are his best arrangements, or is it because I heard them first?
