The pianist Alexandra Sostmann ranks among the select circle of musicians whose repertoire represents such an extraordinarily broad stylistic spectrum that ranges from Baroque to Modern. Effortlessly, fluently, she explores the intricately interwoven paths of musical history – in concert or on her CD Bach & Contemporary Music released in 2014. Her intelligent, sensitive interpretations of works from Bach to Xiaoyong Chen delight critics and the public alike. Thus Dr Thorsten Preuß from Bavarian Radio commented: "Magic moments that make the CD a fascinating voyage of discovery into the depths of time." The highly reputed portal "Musicweb International" puts Sostmann's Bach recordings on a par with those of Angela Hewitt, Murray Perahia, Robert Levin and Vladimir Feltsman, and Fono Forum expresses its high esteem succinctly and to the point: "Musicality and sound score highly!“

Alexandra Sostmann studied with Volker Banfield and the celebrated Bach interpreter Evgeni Koroliov at the Hamburg University of Music and Theatre and with Dr Peter Katin at the Royal College of Music in London, where she gained her concert diploma. She rounded off her musical studies with semesters abroad at the Mozarteum in Salzburg and at the Ecole Normale de Musique de Paris Alfred Cortot. One of her teachers in Paris was Marcella Crudeli.

While still a student, Alexandra Sostmann won the 1st prize in the Caltanissetta International Chamber Music Competition (1998). Other distinctions at international piano and chamber music competitions followed.

Alexandra Sostmann performs both as soloist and chamber musician in notable German concert halls such as Berlin's Konzerthaus, or in Dresden's Frauenkirche as well as internationally, in Rome, Vienna, Zurich, London, Paris, Amsterdam, Lisbon, in South America, the USA and Canada. Among the many orchestras accompanying her are Göttingen Sinfonieorchester, Kammersymphonie Berlin, Cappella Istropolitana, Orquesta Sinfónica de Bahía Blanca, and Banda Sinfonica Municipal de Mar del Plata, Argentina. Apart from her solo and orchestral concerts, she passes on her knowledge and expertise in the context of master classes.

She has performed memorably at festivals, both internationally renowned and regionally prestigious, such as the Schleswig-Holstein Music Festival, the Ruhr Piano Festival, the Festival d'Ile de France, the Central European Festival at Žilina, Slovakia, the Swiss piano festival "Klavierissimo", and the "Sunnisheimer Klaviertage" in Sinsheim, Germany. For over 10 years, Alexandra Sostmann and Judith Mosch co-performed in the internationally successful Duo Villarceaux devoted to piano music for two pianos and for four hands. As in her solo career, her artistic work covers an extremely broad stylistic spectrum. Thus the duo's repertoire comprises famous compositions for two pianos from the Baroque, Classical and Romantic periods as well as rarely performed modern works and diverse first performances. Besides radio and TV recordings, "Duo Villarceaux" has published several CDs on the Thorofon, Phoenix Edition und TYXart labels with works by Ravel, Debussy, Stravinsky, Rachmaninoff, Piazzolla, Bach and contemporary music. Its CD of Stravinsky's "Le Sacre du Printemps" met with huge international acclaim. The reviewer of the "American Record Guide" enthused: "… the two young German pianists are excellent – I’ve rarely heard better unison playing or greater understanding of the Stravinsky idiom.“ The "El Mercurio" (Santiago de Chile) wrote: "It was most beautiful to hear the music radiating in all its strength and rhythmic vitality, with everything that it reveals when courageously explored ... an utterly extraordinary experience."

In the spring of 2015, Alexandra Sostmann gave several concerts in South America, which directly led to further engagements. Thus, in the autumn of 2016, she gave several orchestral concerts in Argentina, including Stravinsky's Concerto for piano and Wind Instruments, which she played, among other concert halls, at the well-known coastal town of Mar del Plata. The public and critics were enthusiastic: "… this music was a gift of God …" ("La Capital", Mar del Plata). In Mar del Plata, Sostmann was officially awarded the status of a "Guest of Honour", and several subsequent engagements led to the planning of an Argentinian concert tour for 2017. In 2017, Sostmann's South American schedule of solo and orchestral concerts will also take her to Chile, where, apart from concert appearances, a number of master classes at the Universidad de Santiago are on the agenda.

Also in 2017, Alexandra Sostmann will continue her successful work with the prestigious TYXart label. In spring, she will record her second solo album to be published in the autumn. As with her successful CD "Bach & Contemporary Music", it will be about exploring fascinating references and relationships between diverse periods of musical history and making them come to life – in a way comparable with the successful concept of the former CD, but ultimately quite different.

Alexandra Sostmann is keen to work with composers and artists from other disciplines such as the choreographer and ballet director Jutta Ebnother and the Nordhausen Company in the production of "La dame aux Camélias". As ballet music for her version of the world-famous love story, Ebenother had chosen works by Chopin and Liszt, which Alexandra Sostmann interpreted on the piano live on stage. She can also be heard as a Lieder accompanist with various programmes, such as "Die Winterreise" with the British baritone Alistair Shelton-Smith. She also works closely with the renowned Chinese composer Xiaoyong Chen.
