Sagi began studying the cello at the age of ten. By fifteen he had already performed with the Haifa Symphony Orchestra. He left Israel in 2000 to study at the Royal Academy of Music with Mats Lidstrom. He graduated his Postgraduate Diploma with Distinction and was also awarded an LRAM teaching qualification.
Sagi won several major awards from the Royal
Academy of Music; the Ferdinand Beck Fund, the
American-Israel Foundation, and the Muriel Taylor National
Competition for Cello among others.
While at the Academy he represented the String department in the finals of the prestigious RAM Club Prize, where he achieved a Distinction and opened the new David Josefowitz Recital Hall. He was also a finalist in the Rostropovich International Cello Competition 2001 in Paris. In July 2010 Sagi was invited by Martha Argerich and Alberto Portugheis to perform alongside them for the 'Argentina 200' festival at Kings Place, London.
Sagi's outstanding talent has been rewarded by lifetime loans of both a Maucotel 1849 cello, as well as a Silvestre et Maucotel, (Paris 1912). He is currently performing on a Guarneri 1720 on loan from an anonymous donor.
Sagi is also the Founder and Chairman of the Israeli International Music Competition and the Bloch Music Competition.
