Konstantin Vassiliev has won prizes at several international composition competitions. He studied guitar with Professor Arkadiy Bourchanov and Professor Reinbert Evers, as well as composition and music theory with Dr. George Haidu. Vassiliev composed chamber music for various types of ensembles, but his work remained focused on his primary instrument, the guitar. His numerous compositions and arrangements have been published in Europe, as well as in Japan, Canada and the USA. His music sounds experimental and innovative. His musical style distinguishes itself by its diversity: from romantic melancholy through impressionistic fantasies and mysticism to contemporary expressiveness. For many years, the composer worked together with famous performers. His music found a firm place in the repertoire of Shin-Ichi Fukuda, Roman Viazovskiy, Irina Kulikova, Eleonora Perretta, Yuri Liberzon, Carlos Bonell, Carlo Marchione, Thomas Müller-Pering, Dimitri Illarionov, Matt Palmer, Maximilian Mangold, Sanel Redžić, Ruben Bettencourt, Aynur Begutov, and other highly regarded musicians. As well as this, many promising young musicians taking part in the "Young Musicians" programme owe their initial successes to Vassiliev's music.
