About the first one, yes: As far as I can tell, they're all new masters by Mark Wilder and Maria Triana (Battery Park Studios), except for the Rosemary Clooney, Such Sweet Thunder, and Black, Brown and Beige, which are, respectively, verbatim copies of CK65506 (Didier C. Deutsch), and Phil Schaap's CK65568 and CK65566 (hence the wrong coda on "Up and Down"—a pity that this wasn't corrected, given that Sony does have a digital master of the correct one, released on the compilation Ralph Ellison - Living with Music, CK 85935).
