The music varies from contemporary classical music to avant-rock: there is a string quartet ("String Quartet 1"), two works for small ensembles ("A Hollow Miracle" and "Palimpsest"), a piece for samples and multiple horns ("From Descartes' Dreams"), a piece for MIDI-instruments ("Numinous Pools for Mental Orchestra"), and an unrecorded Henry Cow number from 1976 ("Hold to the Zero Burn, Imagine").
The Nahuatl term is often translated as "god", but it may have held more abstract aspects of the numinous or divine, akin to the Polynesian concept of Mana.
