This is a two part post.
In the other posts you discuss some organists I am unfamiliar with, as I specialize in jazz organ. How do jazz artists such as Joey DeFrancesco and Larry Young compare w/the organists you discuss, if they do at all?
The 2nd part of this question-jazz players tend to prefer the Hammond B3 or C3-the organs that you are discussing seems to be more in the theatre or classical/pipe genre. Is the Hammond a viable organ for these organists?
