Outsider Art is a familiar concept in the visual arts, Sub Rosa here attempt to compile a collection of pieces that might extend the idea into the sonic realm. They are not explicit about their criteria, but the CD features a wide range of pieces - from several countries - which are mostly naïve, obsessive or autistic, played by people who would be commonly designated, if not crazy, at least highly eccentric. Fascinating, rather than musical, and highly unusual. There are some extraordinary moments here (in particular the first and last tracks). Working outside the recognised discourse of 'music' these pieces, through their resemblance to what is normative, unsettle easy assumptions about what art , or music, is - or does - or is supposed to do. An interesting record and a useful attempt to suggest a positive category of work usually dismissed as aberrant or failed.
