Darmstadt. There he became obsessed with serialism, a post-war method of composition in which elemental parts of the sound (pitch, duration, volume and timbre) are ordered according to row structures. The year after that he studied with Messiaen in Paris and, with a few ground-breaking works, managed to establish himself at the forefront of new music. From the second half of the 1950s onwards he achieved great artistic successes with a freer approach to the principles of serialism. At the WDR-studio in Cologne (which he went on to direct in the 1960s) he experimented with electronica as well as the placement of the orchestra in relation to the audience, extremes of tempo and music from all over the world. In 1964 an ensemble was established, dedicated exclusively to the performance of his work and in 1970 he set up his own music press. In the 1970s his approach to music took a markedly cosmic turn: he wanted to find a way to express his connectedness to the cosmos, nature and his fellow man. With LICHT (1977-2003), a cycle of seven colossal operas, one for each day of the week, he created a work intended to encapsulate the whole of his life. In 2019 Holland Festival, The Dutch National Opera and the Royal Conservatory in The Hague will present a broad selection from the series under the title aus LICHT. From 2003 to his death in 2007 Stockhausen worked on Klang, a comparable cycle about the hours in the day. Lucas (1993) and Arthur (1996) Jussen received their first piano lessons from Leny Bettman in Hilversum. In 2005 the brothers studied for a year with the Portuguese master pianist Maria João Pires. After that came lessons with Jan Wijn and Ton Hartsuiker. Lucas also studied with Menahem Pressler in the United States and with Dmitri Bashkirov at the Escuela Superior de Música Reina Sofia in Madrid. Lucas and Arthur are former winners of the Concertgebouw Young Talent Award (2011) and the Audience Award of the Festspiele Mecklenburg-Vorpommern (2013). In the Netherlands the duo have appeared alongside the Royal Concertgebouw Orchestra, the Rotterdam Philharmonic Orchestra, The Hague Philharmonic and the Radio Chamber Philharmonic Orchestra amongst others, as well as playing internationally with orchestras such as the Dallas Symphony Orchestra, the Hong Kong Chamber Orchestra and the London Chamber Orchestra. During these collaborations they have worked with such conductors as Valeri Gergiev, Jaap van Zweden, Jukka Pekka Saraste, Elihu Inbal, James Gaffigan, Sir Neville Marriner and Frans Brüggen. Arthur and Lucas are also known internationally for their solo recitals. They appeared in the series Meesterpianisten (Master Pianists) and the Robeco-series at the Concertgebouw and gave concerts at the invitation of the former Dutch queen Beatrix. In 2014 the brothers accompanied King Willem-Alexander and Queen Maxima on their first state visit to Poland. In 2010 Lucas and Arthur signed a record deal with Deutsche Grammophon. Their debut CD of works by Beethoven went platinum and was awarded the Edison Classical Audience Award. After a well-received recording of Schubert pieces and a release dedicated to French piano music (Jeux) their fourth CD, of Mozart piano concertos, came out at the end of 2015. This collaboration with The Academy of St Martin in the Fields led by Sir Neville Marriner was awarded the Edison Classical Audience Award 2016. Grammophone UK selected this recording in their top 50 greatest Mozart recordings. With their performance of Mantra Lucas and Arthur take on their first large-scale contemporary work.
