text: Greenwich Trio Together with the Slovenian violinist Lana Trotovsek and Japanese pianist Yoko Misumi, Hauser was a member of the Greenwich Trio, described by cellist Bernard Greenhouse as the "New Beaux Arts Trio". The Trio won a series of first prizes at international chamber music competitions in the UK, Belgium and Italy. The Greenwich Trio had masterclasses with Amadeus Quartet, Alban Berg Quartet, Guarneri Quartet, Beaux Arts Trio, Trio Fontenay, Menahem Pressler, Bernard Greenhouse, Ivry Gitlis, Stephen Kovacevich, Ralf Gothoni, Niklas Schmidt, Arnold Steinhardt, Valentin Erben, and Eberhard Feltz. In March 2008, they performed Beethoven's Triple Concerto with conductor Barry Wordsworth and in September the same year they played in the sold out opening festival at King's Place, London.
  2CELLOS
  Under the name 2CELLOS, Hauser and Šulić recorded an album with Sony Music Entertainment, which was released in July 2011.
  In January 2012, they appeared as the special musical guests on Fox's hit TV series Glee where they performed "Smooth Criminal" in the Michael Jackson tribute episode. This was the first time that an instrumental duo had performed on the show in this guest spot. 2CELLOS' arrangement of the song, which featured actors Grant Gustin and Naya Rivera, debuted at #10 on the Billboard Hot 100 Digital Songs Chart and landed their debut album in the Top 100.
  In late 2012 and early 2013, a second 2CELLOS album, In2ition, was released.
