Sonic Asymmetry provides detailed reviews of various types of creative music. In their own words:
Sonic asymmetry is an attempt to share the extraordinary adventure in the holistic appreciation of the frequency, amplitude, duration and form of sound waves. For some, this will be music, for others just noise. This electronic (and mute) internet medium will occasionally share impressions from the aural confrontation with the musical output from many traditions, milieux, schools and styles. Some of the artists have functioned outside any recognizable movement, others preferred to evolve within more familiar canons. There is nothing that defines their belonging to one category, other than the capacity to surprise our auditory system.
