This week's Podcast is another special long-length edition, for which Editor Martin Cullingford is joined by Rob Cowan, Gramophone's expert on historic and archive recordings and the author for 30 years now of our monthly feature devoted to the area, Replay. Why should we listen to historic recordings? What can we learn from them, and which artists, many decades on, still offer listeners such extraordinary joy and insight? Across more than 45 fascinating minutes Rob addresses these questions, and we play excerpts from some absolute highlights from the archives.
