Main were a British ambient band formed in 1991 by guitarists Robert Hampson and Scott Dowson, the former members of Loop. They combined ambient sound with layers of electric guitars and dark, foreboding emotional overtones. In 2006 Hampson announced that Main had been effectively disbanded in favour of his solo work.
In October 2010, Hampson announced that he would be reactivating Main again, which along with his solo acousmatic work, he will start performing and recording as a more collaborative process with fellow sound artists. In 2011, German composer Stephan Mathieu joined Hampson for a current incarnation of Main.
