The instrumental concerto occupies a very prominent place in the music of Krzysztof Penderecki. This fact is related to the great life force exhibited by this genre in twentieth century and in contemporary music. It is stimulated by commissions from virtuosos and by audience expectations; also favourable is the composers’ flexibility in approaching the form, whose chief idea continues to be the juxtaposition of the solo instrument and the orchestra. The violin and viola works presented on this CD are not only interesting, concrete realizations of the concertare idea in Penderecki’s music, but also examples of this composer’s sonic language and style in the period of his creativity which Mieczyslaw Tomaszewski called a “time of dialogue with the regained past”.
