MARIAN BORKOWSKI (b.1934): Spectra for Solo Percussion (Stanislaw Skoczyński], Visions I for Cello {Tomasz Strahl), Psalmus for Organ (Andrzej Chorosiński), Images II for Any Solo String Instrument (Patricja Piekutowsla [violin]), Vox for Any Solo Wind Instrument (Zdislaw Piernik [tuba]), for Piano: Toccata (Marcin Tadeusz Łukaszewski), Interludes Romantiques (Marian Borkowski), Fragmenti (Andrzej Dutkiewicz).

Description: Most of these works are from the 1970s, when Borkowski had arrived at his mature, experimental style, featuring graphic notation, aleatoric techniques and extended instrumental techniques. Only the earliest piece, the vigorous Toccata (1960) is relatively conventional, somewhat Bartókian. Fragmenti (an impressive work, juxtaposing various styles including bell sonorities in Messiaenic harmony) and Visions I, a couple of years later, see the composer transitioning away from this style, with the introduction of clusters and sonorist timbres. The exception is Interludes (1976), composed for a specific project that required sentimental pastiche. Spectra is a dramatic percussion extravaganza, exploring and contrasting instrumental timbres.
