The Arditti Quartet enjoys a world-wide reputation for their spirited and technically refined interpretations of contemporary and earlier 20th century music. Several hundred string quartets and other chamber works have been written for the ensemble since its foundation by first violinist Irvine Arditti in 1974. These works have left a permanent mark on 20th century repertoire and have given the Arditti Quartet a firm place in music history. World premieres of quartets by composers such as Harrison Birtwistle
