The Amadeus Quartet (which their friends often called the Wolf Gang), gave its first concert in the Wigmore Hall, London in 1948. The hall was full and hundreds of people were turned away. After this concert they were invited to perform all over the world. They became the most famous string quartet group of their time. They made about 200 recordings. They were especially known for playing quartets by the great classical composers Mozart, Beethoven, Schubert and Brahms, but they also played works by 20th-century composers such as Bartók and Benjamin Britten (who wrote his third quartet for them).
