Dean's compositional style is known for creating dynamic soundscapes and treating single instrumental parts with complex rhythms. He shapes musical extremes, from harsh explosions to inaudibility. Modern playing techniques are as characteristic for his style as an elaborate percussion scoring, often enriched with objects from everyday life. Much of Dean's work draws from literary, political or visual stimuli, transporting a non-musical message. Environmental problems are the subject of "Water Music" and "Pastoral Symphony," while "Vexations and Devotions" deal with the absurdities of a modern society obsessed with information.
