This week's podcast is devoted to exploring the music, life and legacy of the greatest genius of Baroque music – and arguably of all music – JS Bach. Editor Martin Cullingford invited Bach specialist and Gramophone reviewer, the Royal Academy of Music's Principal Jonathan Freeman-Attwood, to talk about the composer of some of the most profound masterpieces ever written. Gramophone Podcasts are presented in association with Wigmore Hall. Musical excerpts are taken from: the Cello Suites by David Watkin on Resonus; the Sonatas and Partitas for Solo Violin by Rachel Podger on Channel Classics; the Goldberg Variations by Beatrice Rana on Warner Classics; and the St Matthew Passion conducted by Masaaki Suzuki on BIS.
