Tosko Iliev was born on Sept. 1st, 1895 in Parvomaj (Bulgaria). After finishing his law study in Sofia, he went to Vienna in order to study voice now.
Before becoming a soloist, he was a choirmaster; as late as 1934, he had his debut in Stara Zagora (in "Gergana" by Atanasov), where he was to remain
throughout his career (which ended in 1943) and longer, since he was also that theatre's manager from 1946 to 1954.
