This Sunday Musica Antiqua continues its series on the Boston and Madison Early Music Festivals with 3 interviews and lots of music. First off we’ll hear Patrick Dunachie, the newest member of the King’s Singers, describing his role and what has kept that group going strong for 50 years. The King’s Singers sang at BEMF and will be in Madison at Shannon Hall next April. At 9:00am, Daphna Mor and Cheryl Bensman-Rowe come to the WORT studios for a live conversation about MEMF and the concert Tuesday night that features Daphna and her group playing Sephardic and Mediterranean music. An interview with Ronn MacFarlane and Ayreheart (a self-styled “early-music rock band”) wraps up the show with Dowland as you’ve not heard him before. All on Musica Antiqua, which airs every Sunday from 8am to 11am on WORT, 89.9 FM, Madison; also streaming live and archived at wortfm.org. (King’s Singers photo by Marco Borggreve)
