The arresting tone of Bulgarian violinist Irina Borissova is well-suited to the unusual selection of works on this recording. All use different techniques to convey high levels of tension and drama. This is particularly true of the opening Violin Sonata, Op. 1, by fellow Bulgarian Pancho Vladigerov, written in 1914 at a mere 15 years of age. Spikey and a little overwrought with a lovely lyrical Andante, this deeply Romantic sonata is an extraordinary achievement.
