The parent company of San Diego’s daily newspaper has finalized a deal to become the principal sponsor of a series of local and national radio broadcasts of the San Diego Symphony, a project which will also allow the orchestra to archive its concerts and create marketable recordings from the master tapes. The 14-part local series will be carried by KPBS radio beginning in summer 2006, and the 6-concert national series will be distributed by National Public Radio, making the ensemble one of a small handful of American orchestras with a national radio presence. The recordings will all be made in high-definition, and the SDS plans to quickly turn them into in-house CDs for wide release.
