Award-winning Atanas Ourkouzounov is one of Bulgaria's foremost composers and has written prolifically for the guitar. These five sonatas reveal elements of Bulgarian national music- sometimes through a textured soundscape that includes percussive elements- cast in forms that are often rhythmically asymmetric. Teeming with complex harmonies, contrapuntal effects and poignant depth, the sonatas are a vivid contribution to the contemporary guitar repertoire. Kostas Tosidis is a classical guitarist, performer, researcher and a pedagogue in 3 different institutions. Since September 2016 Tosidis has been a PhD candidate in the Royal Conservatory of Brussels. His topic of research explores the possibilities of playing arrangements of contemporary pieces for cello, violin and viola on the guitar without losing the music's intention or style. Part of that is his arrangement on the monumental work by G. Ligeti 'cello solo sonata', published by Schott Edition. His doctoral research includes commissioned works by composers such as Atanas Ourkouzounov, Marios Joannou Elias, Feliu Gasull, Marco Dottlinger, Giannis Papakrasas and Yorgos Nousis.
