Ike Quebec can be divided into "early" Ike, and Ike just before he died. Early on he was almost R&B, but switched to a very "Soulful" sound that was in no way related to "Soul Jazz', which is why I prefer individual definitions as opposed to "Wiki" definitions.
Correct me if I'm wrong Alex, but I believe you were referring to "jazz with soul" as opposed to Wiki "Soul jazz" when you referred to Jimmy Smith.
While Ike Quebec is jazz with soul, he was never "Soul jazz". There are many different sounds that can be called "Soul Jazz"; so many that I prefer the individual 'aficionado's definition of the term. How about some "jazz Funk".

This is "new jazz"; meaning more in fashion now.

I suppose variety is the spice of life; Something Old, Something New, Something Borrowed, Something Blue.
