I would like to know the chronological relationships among the RIVERSIDE RECORDS related labels and series, and their dates of operation. e.g. WASHINGTON 700 series was used to reissue many of the Riverside Folklore 12-600 series and other folk/world albums from other riverside labels (Judson, etc), seems to have started out as a classical label (400 series many Arthur Balsam albums), and later reissues of classical vocal material. When were each of these active? The Riverside 800 Specialty Series appears to have drawn material FROM, or provided material TO other series. Which way was it? RIVERSIDE (10" 1000, 2500, 8000 series)(12" multitudinous series), OFFBEAT, WONDERLAND, GOLDEN WONDERLAND, GOLDEN, JUDSON, BATTLE, what else?? What was the relationship with Golden (AA Records), and other such relationships?? Were these independent labels, was material licensed or sold outright?..... Hope someone or 2 or 3 can provide an overview and details. Thanks! Best wishes, Thomas.
