These two discs reveal Wolff as a composer fully exploring, in different ways, the continuum between music which is highly fragmented, embracing extended silences [composed or indeterminate], to that which is more progressive and seemingly driven, albeit taking in disarming and unconventional routes. As a body of repertoire, these works are remarkable for their freshness of musical thought and energy (John Cage considered Wolff to be the most 'musical' of the experimental composers).
