Greenwich Mean Time (GMT) is a time system originally referring to mean solar time at the Royal Observatory in Greenwich, London, which later became adopted as a global time standard. It is arguably the same as Coordinated Universal Time (UTC) and when this is viewed as a time zone the name Greenwich Mean Time is especially used by bodies connected with the United Kingdom, such as the BBC World Service, the Royal Navy, the Met Office and others.

Before the introduction of UTC on 1 January 1972 Greenwich Mean Time (also known as Zulu time) was the same as Universal Time (UT) which is a standard astronomical concept used in many technical fields. Astronomers no longer use the term "Greenwich Mean Time".

In the United Kingdom, GMT is the official time only during winter; during summer British Summer Time is used. GMT is the same as Western European Time.

Noon Greenwich Mean Time is rarely the exact moment when the sun crosses the Greenwich meridian (and reaches its highest point in the sky at Greenwich) because of Earth's uneven speed in its elliptic orbit and its axial tilt. This event may be up to 16 minutes away from noon GMT (a discrepancy calculated by the equation of time). The fictitious mean sun is the annual average of this nonuniform motion of the true Sun, necessitating the inclusion of mean in Greenwich Mean Time.

As a guest player and collaborator she has played rock (Jeff Beck), hip-hop (Urban Species) and theatre/film music.

I just love crafting and shaping sounds. Actually, many of the sounds that I work with start off as organic instruments - guitar, piano, clarinet, etc. But I do love the rigidity of electronic drums... I would record live drums, and then I would spend a day editing them to take the life out of them. I like to breathe my own life into these sounds, and I do try to keep the 'air' in the music. Some people think electronic music is cold, but I think that has more to do with the people listening than the actual music itself.
