In 1997, Laurent Albrecht Breuninger achieved international attention when he placed second at the Queen Elisabeth Competition in Brussels. The same year, he won a composition prize at the Brandenburg Summer Concerts for his first string quartet. Simultaneously, his debut CD was released, containing another of his works, a Passacaglia for solo violin. This was followed by recordings as a performer of compositions for violin/viola and piano by George Enescu, the complete works of Eugène Ysaÿe and concertos by Charles Auguste de Bériot, Rodolphe Kreutzer, and Felix Weingartner.
Laurent Albrecht Breuninger's rediscovery of the works of Karol Lipiński, a colleague and rival of Paganini, attracted international attention. As soloist, Breuninger debuted at age 12 with the Budapest Chamber Orchestra led by Vladimir Spivakov. Since then, he has worked as a concert artist. Recent appearances include the Georges Enesco Festival in Bucharest, the Tokyo Symphony Orchestra and Korean Chamber Orchestra.
Former students from his class have been hired for leading positions in renowned German and international orchestras, such as the Munich Philharmonic, the Mitteldeutscher Rundfunk (MDR) Leipzig Radio Symphony Orchestra, Gürzenich Orchestra Cologne, and Mozarteum Salzburg.
