System 7 is the collaborative project of Steve Hillage and Miquette Giraudy. Their style ranges from trance, techno, ambient and progressive house, with themes that often contain earth, ocean & space references with the added element of Steve's distinctive heavily processed guitar. They released their first album in 1991 and since then have released over a dozen albums and singles. While Hillage and Giraudy represent the core of the group many of their tracks are made with a wide range of guest artists including Derrick May, Alex Paterson, Carl Craig and Laurent Garnier. Trivia: the project was named after Apple's OS 7.
