Following last year's Gramophone Award-winning solo Verdi album, Ludovic Tézier returns to the composer – and a couple of others – for his latest Sony Classical  release, 'Insieme' (Together). Joining Jonas Kaufmann he explores some of the great tenor-baritone duets of the operatic repertoire with the Orchestra dell'Accademia Nazionale di Santa Cecilia conducted by Sir Antonio Pappano. He talks to Gramophone Editor-in-Chief James Jolly.
