Kaffe Matthews has been making and performing new electro-acoustic music since 1990. She is acknowledged as a leading figure and pioneer in the field of electronic improvisation and live composition making on average 50 performances a year worldwide. In 1997 she established the label Annette Works, releasing the best of these events on the six cd's, 'cd Ann', 'cd Bea' , 'cd cecile' ,'cd dd', 'cd eb and flo' presenting an annual document of ever developing sound worlds.
Currently she is directing the collaborative research project Music for Bodies with multidisciplinary professionals and the community, bringing new music and some ideas about listening to everyone.(NESTA Dreamtime Fellowship, 2005).
Kaffe has become known for making site-specific sound works live, playing in the dark in the middle of the space, the audience surrounding her, the sounds moving around them. She uses self-designed software matrices through which she pulls, pushes and reprocesses sounds live, using microphones, a theremin, and feedback within the space; the site then becoming her instrument. It is this practice that she has shifted to sonic furniture building, with Sonic Bed_London (Distinction ,Prix Ars Electronica,2006) and the Worldwide Bed project being a central pin in this ongoing project.
Kaffe also collaborates and has worked and performed with many artists worldwide. She has also been making a growing body of composed works through collaborations with a variety of people, things and processes. From working with NASA astronauts researching the sonic experience of space travel, making BAFTA awarded Weightless Animals: kites and the weather on an uninhabited Scottish island,Sanda, Weather Made; taut Wires in the Australian outback with Alan Lamb; Touching Concrete Lightly for MIMEO and the Oscar Niemeyeyer Pavilion 2003, Serpentine Gallery; and the innovative Radio Cycle, a concept and works for maps, bikes and radios.
