BOSTON IS indeed a city passionate about classical music, as critic Jeremy Eichler notes (“A new WCRB, and a shrinking classical dial,’’ Living/Arts, Dec. 18). As we begin our stewardship of 99.5 All Classical, we embrace and respect the views of listeners as we launch our initial plans. But we can all agree on one thing: If WGBH had not stepped up to purchase WCRB, Boston would have only seven hours a day of classical music on the radio, instead of the 24 hours a day we have preserved. And those new 24 hours will include all of the unique concert programs of the Boston Symphony Orchestra, including Tanglewood and the Boston Pops, as well as a host of live performances of local and visiting artists from the WGBH studios. As audiences listen to us, we’ll listen to them as we strive to deliver what Eichler suggests, an exciting 21st century classical public radio service.
