Audio virology is not a metaphor. It is to be taken literally. It maps real processes of mutation, transmission, contagion and memory within music culture.

Most music culture these days runs on systems and networks devised to deal with the aftermath of thermonuclear war. Music culture has a habit of using these moods and machines in creative, unintended ways.

When a country is at war or in economic depression, underdevelopment or tightened security, it sets an affective tone or mood, which seeps through into everyday life via all kinds of channels.

Basically, there were three aspects of dub that influenced dubstep. The most important was playing the instrumental versions of vocal garage tracks, which was a little like what dub was to reggae - the instrumental of a full vocal.The second was dub as a methodology, which, for me, is apparent in all dance music: manipulating sound to create impossible sonic spaces using reverb, echo and such. The third is the influence of the genre called dub. (It became a cliché actually, through sampling old Jamaican films and soundtracks, and adding vocal samples.)

Because we live in a condition of ubiquitous music and media, and near infinite technological memory, it is much easier for local cultures to find an audience that resonates with their music, whether local or globally.

There is an uninformed myth circulating just now that makes dubstep way too important in the musical universe - don't believe the hype.

A one-word book does appeal to me.
