Guys I knew at RCA told me that the reason for all the jazz recorded in the 50s, and to a lesser extent the 60s was - (heh!) nothing to do with a 'cultural mission' on the part of senior management but a need to offset, for tax purposes, the incredible profits from the Elvis Presley catalog. The money only went as far as production though. There was never any intention to market or promote the stuff. A tax loss was what was required. Our silver lining I guess.
