Since the age of 17 Leon Bosch has played chamber music as a guest with the greatest players and groups in the world, including Pinchas Zukerman, Elisabeth Leonskaja, Ivry Gitlis, the Lindsays and the Brodsky Quartet.
His work also reflects his South African roots and in 2017 he founded the Ubuntu Ensemble with other UK-based South African musicians, in the spirit of connection after which the ensemble is named. In 2021 the group will perform the world premiere of a quintet by South African composer Peter Klatzow for the African Concert Series at London’s Africa Centre.
Leon also founded I Musicanti, with which he performs neglected chamber works by great composers as well as great works by neglected composers, alongside like-minded musical friends. He has also commissioned chamber arrangements of well-known concertos for the group, including by Beethoven, Mozart, Mendelssohn and Bruch, adding significantly to the chamber music canon. He has had more than 250 pieces written for him and his ensembles.
