Norman Lebrecht talks to the American composer and conductor John Adams in the week that he conducts his opera Nixon in China at the BBC Proms. Adams who was born in Massachusetts is one of the most celebrated composers alive. Many of his pieces are in the repertory, including his operas Nixon in China, the Death of Klinghoffer and his opera about Robert Oppenheimer, Doctor Atomic all of which receive stagings around the world and all of which he talks about in this interview. Adams also talks about his early years learning the clarinet, imagining music in his head as he did his paper round and starting to conduct and compose. Adams turned down the chance to go to Tanglewood to learn conducting and instead drove to the West Coast to broaden his experiences. Here he encountered some of the early minimalist composers and was involved in performing concerts of music by John Cage. As he developed his artistic personality Adams rejected both Cage's ethos and that of the modernists. Adams has always been concerned with music as expressing feeling and was as open to influences from rock and pop music as he was to music of classical composers. In this sense he believes his openness to a variety of influences makes him closer to a fellow New Englander, Charles Ives. John Adams also tells Norman about his experiences with the US Homeland security, and how he was blacklisted and about his political views in this honest conversation. Producer Tony Cheevers.

Norman Lebrecht talks to the great Italian conductor, Riccardo Muti, music director of the Chicago Symphony Orchestra. Muti's career has spanned key orchestras including the Philharmonia Orchestra, the orchestra of La Scala in Milan and the Vienna Philharmonic. Elegant and erudite, this is the first extended interview Riccardo Muti has given the BBC. He reveals his thoughts and feelings about Verdi and Rossini, about his professional relationship with his mentor, Herbert von Karajan, and about his sense of being an 'outsider' in the world of music, a normal man with an extraordinary job.

Norman Lebrecht talks to the young Latvian conductor Andris Nelsons currently music director of the City of Birmingham Symphony Orchestra. Born in Riga to musical parents Nelsons cites one of his earliest formative musical experiences as a performance of Wagner's Tannhauser which his parents took him to when he was just 5. He later took up the trumpet and eventually became a professional player in the Latvian National Opera Orchestra. He had conducting lessons with Neeme Jarvi and then came to the attention of Mariss Jansons whilst playing on tour with the Oslo Philharmonic and subsequently had lessons with him. He eventually rose to become chief conductor of the Latvian National Opera at the age of 25 and it was there he met his future wife the soprano Kristine Opolais. Nelsons has conducted at the Met, the Royal Opera House and at Bayreuth where he made his debut in 2010 with a new production of Lohengrin and where he returned this year. In 2007 he became Music Director of the City of Birmingham Symphony Orchestra having previously only conducted them in a private concert and a recording session, never at any public concerts. His present contract with them runs to 2014 and he appears with them at the BBC Proms this week.
