Who are Serbia's Eurovision entry Sanja Ilić & Balkanika?

67-year-old composer and architect (!) Sanja Ilić has been making music professionally since age 12, and, though he has written many songs for the competition, had yet to make an appearance himself until this year.

At 16, he wrote the song Baj baj baj which was sung by singer Bisera Veletanlić at Eurovision 1976 (representing Yugoslavia) at The Hague. She came in third. He composed further entries in 1982 and 1984.

He started up Balkanika in 1998, a group of five vocalists, two percussionists, two guitarists and one flautist. They also incorporate old Balkan instruments into their music from time to time to add to their traditional sound.
