Many of his works are available through the Canadian Music Centre Distribution Service.

Carastathis' compositional style has gone through various transformations. Early works are strictly atonal with heavy emphasis on serial models. Newer works display a mixture of atonal and tonal idioms with an underlying modal quality. Conventional harmonies coexist with, emerge from or result to pitch-mass sonorities. Counterpoint of instrumental timbres play an important role in all of the composer's orchestral works. Carastathis favours non-symmetrical rhythmic designs with abrupt dynamic changes and extensive use of syncopation. Folk elements often appear in his more recent works. His latest interests include integration of elecroacoustic composition and computer art/animation. Recent representative works are Cubismos, Water Colour and Full of Stars with video art by Mark Nisenholt.
