On another website, Chuck Yates has provided an explanation for Jackie’s move from Syco / Columbia to Sony Masterworks:
The music industry is typically a convoluted and labyrinthine corporate structure forever dynamically in motion. This minor change in label names isn’t unusual.
Sony Music Entertainment (Parent)
SYCO Music/SYCO Records, subsidiary of SYCO Entertainment
Distributors, Sony Music Entertainment (UK)
Columbia/EPIC Label Group (US)
Sony Masterworks record label: (Genre: Classical, Jazz, Show Tunes) is the result of a restructuring of Sony Music Entertainment’s classical music division. Before the acquisition of Bertelsmann’s shares in the former Sony BMG, the label was known as Sony BMG Masterworks.
Sony Masterworks shares the same parent, or umbrella, as Arista Nashville, Columbia Nashville, RCA Records, RCA Nashville, Epic Records, Columbia Records, Epic Records, and several others.
As far as Jackie is concerned the changing of the label name is little more than moving the deck chairs on a cruise ship. Sony appears to be simply categorizing the artists by genre.
