MASH was formed in 1991 by EAM composer Magnus Alexanderson and visual artist Sachiko Hayashi. MASH's focus has always been to explore various aspects of (inter-)relation between audio and visual, which has resulted in experimentations within several media and formats: multi-media performance, single channel videos and audio-visual interactive performance.

MASH's first project was a multi-media/intermedia project called  "FU (風)." Between 1991 and 1992 "FU (風)" engaged a Butoh dancer, a modern dancer and a violinist at different stages of development, travelled through Sweden and was shown at 7 different cities in Sweden including Folkens Museum in Stockholm and Uppsala Museum of Art.

MASH then moved on to single-channel videos.  These works have been shown widely internationally including such venues as Not Still Art Festival in New York, European Media Art Festival in Osnabrück, Germany, Transmediale in Berlin, Boston CyberArt in Mass. USA , and Radiator - New Media Art Festival in Nottingham, UK . One of MASH videos, "Stretched in Dark" (part of MASH video trilogy), was commissioned by the National Council of Concerts in Sweden, and the whole trilogy was chosen by the same institution for a national tour and was shown at 8 different cities in Sweden in 2000-2001.

Since 2008 MASH has been exploring interactive audio-visual performances.  For more info, please go to "Projects".

The music of "FU (風)" and "Stretched in Dark" is now included on audio CD "Stretched in the Dark," a compilation of EAM works by Magnus Alexanderson, released by Elektron, 2006.
