Uros Spasojevic was born in 1985 in the City of Valjevo, Republic of Serbia. He began studying the violin when he was nine years old. At fifteen, he started playing bass guitar and double bass. At seventeen, he played double bass in the youth jazz big band in his home town. Two years later, he moved to Belgrade and gained significant playing experience in both studios and live performances with prominent pop and rock artists from Serbia. He also performed throughout Europe with ethno-music groups. This helped him become especially familiar with the ethno music of the Balkans and World music. In 2010, he returned to Valjevo and formed his first acoustic jazz trio and quartet. In recent years, he has been working intensively to popularize jazz and fusion music in his home town.
