Kostas Tosidis is a classical guitarist specialising in contemporary music.

He completed his Habilitation at the Mozarteum University Salzburg in 2024.
He studied with Gianni Papakrasas at the Agios Pavlos Conservatory in Thessaloniki, graduating with distinction and receiving first prize in his year. He continued his studies with Eliot Fisk and Ricardo Gallén at the Mozarteum University Salzburg, completing his master’s degree with distinction in 2009 and subsequently being appointed assistant to Eliot Fisk.
He was a founding member of the Miscelanea Guitar Quartet, an ensemble dedicated to developing interpretations of original works for guitar quartet. With the quartet and as a soloist, he has won several international prizes. His concert activity has taken him throughout Europe and the United States, and he has recorded five CDs featuring solo and chamber music repertoire. His most recent recording, dedicated to the five sonatas by Atanas Ourkouzounov, is scheduled for release on the Naxos label.
He is currently pursuing a PhD at the Royal Conservatory of Brussels. His research examines the possibilities of performing arrangements of contemporary works originally written for cello, violin and viola on the guitar while preserving their musical intention and style. This includes his arrangement of György Ligeti’s Sonata for Solo Cello, published by Schott. His doctoral project also includes commissioned works by composers such as Atanas Ourkouzounov, Marios Joannou Elias, Feliu Gasull, Marco Döttlinger, Giannis Papakrasas and Yorgos Nousis.
