He entered the Berlin “Hanns Eisler” conservatoire as an extraordinary student at the age of eleven. Now he collaborates with the great names of music such as Zubin Mehta, Christoph Eschenbach, Rolando Villazón, Cameron Carpenter, Anggun, David Foster and Fazil Say. He is also often to be seen at mass-media events like Miss World or Miss Earth, the Davis Cup, EXPO in Milan or the Fashion Week in Paris.
Iskandar is strongly committed to educational projects for children in the Asian Pacific region, in collaboration with UNICEF or WWF. Supported by KOMPAS Gramedia, Indonesia’s biggest media group, he has organized charity events to finance musical instruments and instruction for street children.
His personality and energy are aptly summed up by the string players’ house magazine The Strad : “Iskandar Widjaja, a true force of nature.”
He plays the “Stephens” 1690 Stradivari and an 1875 JB Vuillaume.
