The group gave its first performance as the Amadeus Quartet in the Wigmore Hall, London on Jan. 10, 1948. They were soon performing in concerts, festivals and masterclasses all over the world. The quartet made about 200 recordings, among them the complete quartets of Ludwig van Beethoven, Johannes Brahms, and W. A. Mozart. They also performed works by such 20th-century composers as Béla Bartók and Benjamin Britten (who wrote his third quartet especially for them).
