Lazar Ostojic (Beograd, 1987) graduated from the Department of Classical guitar in 2012. Since his primary music education years (1998-2003), he started putting sketches on potential music pieces. In 2006 he took the role of bass guitarist in one young rock band from Belgrade, making and performing the band’s original tunes. Three years later, he founded a new band that is active to the present. After another three years, he went to Groningen, the Netherlands. At Prince Claus Conservatorium, he brought Albatross Bass Bird Guitar to the world (he graduated with the project in June 2014). Here, the artist united strings of bass guitar and classical guitar on one guitar body and instrument neck, playing original arrangements of folk songs from the Balkans. Back in the days of his studies in Beograd, he taught in several music schools as a guitar teacher, to where he returned in 2015. Besides the teaching activities, where many awards and results followed, he continued playing and making music in the rock band and formalizing formerly written sketches to music pieces and methods in music. All the periods mentioned above (Beograd – Groningen – Beograd) were spiced with the finalization of several compositions for guitar and guitar in chamber music (Vienna, Beogradsko netradicionalno kolo, Poker u smak sveeeta, Bio sam u setnji po starome gradu, and many others). The music was recorded Lazar Ostojic himself and by colleagues guitarists. One of these collaborations resulted in the publication of the piece he dedicated to the guitarist Mak Grgic, called Stairway to the Balkans, released along with the other pieces on a CD named Balkanisms (Naxos, 6/2019). He gave concerts with the band, classical guitar, and Albatross and performed original works and arrangements in public.
