Conductor Daniel Barenboim has given a "concert for peace" in the Spanish town of Oviedo in honour of late Palestinian author and friend Edward Said.
Daniel Barenboim was married to the late cellist Jacqueline Du Pre
Barenboim and Said co-founded an orchestra of Arab and Israeli musicians to promote peace and friendship between Israel and Palestine.
The pair were jointly awarded the Prince of Asturias Award for Concord in Oviedo in 2002. Said died in 2003.
The orchestra is due to play in Buenos Aires, London and Ramallah.
Known as the West-Eastern Divan orchestra, it consists of approximately 100 musicians including 38 from Egypt, Jordan and Lebanon and 37 Israelis.
Said's widow, Mariam, was among those in the audience at Oviedo where the programme included works by Mozart, Mahler and Carl Maria von Weber's comic opera Abu Hassan.
Israeli pianist Barenboim, 62, was married to the renowned cellist Jacqueline du Pre.
He has announced that he will step down as music director of the Chicago Symphony Orchestra next year. He remains general music director of the Berlin Opera.
