Lazar Nikolov (b. 1922) has included in this CD three works created in the 1990-1992 period, performed at the New Bulgarian Music review and in concert. His music has been marked as avant-guard and referred to the latest trends of 20th century compositional output. In his latest works the composer synthesises devices and techniques of serial, atonal and aleatoric music. The use of Bulgarian metres and modes has always lent a specific, national character to his art which has become a model of innovative thinking. Of particular originality is the composition Metamorphoses No. 4 for 12 violoncellos, dedicated to Prof. Zdravko Yordanov. This is yet another proof of Nikolov's ability to work with timbres, to discover sonorities and new performer's techniques.
