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.

Norman Lebrecht meets celebrated impresario Lilian Hochhauser, who along with her husband Victor, introduced British audiences to some of the greatest Russian musicians of all time, during the fraught period of soviet rule. Now in her eighties, Lilian - from a Jewish Ukrainian background - recalls the Cold War period which saw her and Victor pushing cultural and political boundaries to bring some of the most feted names in Russian music to Britain for the first time. Everyone from Rostropovich, Richter and Oistrakh through to The Borodin Quartet and the Kirov Ballet recieved their London debuts thanks to the Hochhausers.

Norman Lebrecht meets Hungarian conductor Iván Fischer, who looks back on a career characterised by ground breaking musical achievements and occasional political controversy. Fischer recalls his elite musical education under communism, singing as a boy in the opera house where Gustav Mahler was once director. Being taught by both Nikolaus Harnoncourt and Hans Swarowsky during his studies in Vienna, where he initially set out to become a cellist, gave Fischer a unique musical perspective. He remembers what made both teachers great and how they impacted in his later decision to found The Budapest Festival Orchestra, alongside gifted pianist and countryman Zoltán Kocsis. Fischer describes the jealousy and bad feeling which initially greeted the new orchestra, and why his relationship with Kocsis deteriorated. He talks frankly about his discomfort with Kocsis's perceived closeness to Hungary's rightist political regime, and why he will continue to speak out against it. Iván Fischer has always been musically motivated by change: the desire to alter the status quo and unlock the potential of the musicians he conducts - he speaks passionately about what he sees as the crisis being faced by the modern symphony orchestra, and how they need to be reinvented or face extinction.

Norman Lebrecht meets pianist Menahem Pressler, founder of one of the most prolific and influential piano trios of all time: The Beaux Arts. Pressler looks back on a career which began in Nazi Germany, before he emigrated to Israel in 1939 and went on to win The Debussy Piano Competition in 1946. He recalls the teachers who helped him as a young pianist, including a German who defied the Nazi regime in continuing to teach him after it became illegal to do so, and his lessons with celebrated pianists Egon Petri and Leo Kestenberg. Pressler remembers how he formed The Beaux Arts Trio with violinist Daniel Guilet and cellist Bernard Greenhouse almost by accident while living in New York, before making their debut at Boston's Tanglewood concert hall in 1955. He reflects on the trio's changing personnel, which has seen Pressler as the one constant member while five violinists and two cellists have come and gone. Still performing now at the age of eighty eight and a renowned teacher and mentor to top chamber musicians like the Emerson and Ebène String Quartets - Menhem Pressler reflects on what makes a great chamber group and how music has sustained him throughout a long and distinguished career.

The Lebrecht Interview is the interview series that runs during the Proms season in which the writer and broadcaster Norman Lebrecht talks to key figures in the world of classical music. Today, Norman is in conversation with the Venezuelan conductor, Gustavo Dudamel, Music Director of the Los Angeles Philharmonic and of the Simon Bolivar Symphony Orchestra of Venezuela. Dudamel is a walking advertisement for the success of the extraordinary El Sistema music education project in which poor children in Venezuela are given the opportunity and financial support to train in an orchestra. A product of that system, Gustavo Dudamel has become a byword for joyous, passionate music making, his concerts celebrated almost as religious events. In this interview, Norman Lebrecht talks to the man behind the hype. How heavily does Dudamel feel the weight of reputation?

In the last edition in this series, Norman Lebrecht talks to the great English singer, Dame Janet Baker. The Yorkshire-born mezzo-soprano has mostly been known for her performances in operas by Mozart, Monteverdi, Purcell and Berlioz. In the concert hall she was renowned for her lieder singing especially Mahler, as well as English music, in particular the works of Benjamin Britten with whom she was much associated. The clarity of Janet Baker's voice and the dramatic intensity of her performances have given her a legendary status in the international worlds of opera and song.

Edward Gardner is the Music Director of English National Opera and about to become Principal Guest conductor of the City of Birmingham Symphony Orchestra. He talks to Norman Lebrecht about his career to date. Gardner was appointed to the post at ENO in 2007 while in his early 30s and began by conducting a new production of Britten's Death in Venice. He was born in Gloucester and began his musical life as a chorister at Gloucester Cathedral. He later went to Eton where he enjoyed the music making and education and then went to Cambridge where he says he enjoyed the conducting and performing that he did there rather than the more academic side of the course. The Royal Academy of Music followed but before leaving he was already working in the summer at the Salzburg Festival as a repetiteur encountering some of the leading conductors and operatic productions of the time. This experience has influenced some of his choices at ENO. He then worked with Mark Elder at the Halle Orchestra. So choral music and opera were both at the heart of his musical training. In 2004, before he was thirty, he was invited to be Music Director of Glyndebourne Touring Opera, an experience, he says which gave him the opportunity to conduct operas like La Boheme 20 times in different venues and acoustics around the UK. Since taking up the baton at ENO he has been involved with the planning of the company's repertoire and has conducted new productions of operas by Saariaho, Verdi, Bartok and Puccini. He talks about the challenges the company faces. How it has improved its image and work after a period of decline and argues with Norman about the continuance of the company's policy of performing operas in English. Producer Tony Cheevers.
