Berlin-based musician and media artist Michael Vorfeld celebrates the 20th anniversary of his unique sonic explorations with a new volume of his Glühlampenmusic (Light Bulb Music). Mastered by Rashad Becker. Michael Vorfeld is a musician and media artist, plays percussion and self-designed string instruments, and realizes electroacoustic sound pieces. He works in the field of experimental, improvised music and sound art, realizing installations and performances with light and sound, and working with photography and film. In addition to his solo activities, he is a member of various ensembles and collaborates with artists who work in many different art forms, e.g. Burkhard Beins, Mazen Kerbaj, Ute Wassermann, Reinhold Friedl, to name a few. Based in Berlin, his list of activities includes numerous concerts, performances and exhibitions in Europe, America, Asia and Australia. Michael Vorfeld participated in the documenta 8, Kassel with the sound performance group "Heinrich Mucken".

Since the mid-1980s, Vorfeld has been realizing a multiplicity of partly site-specific light works (most of which also included sound) and where the incandescent lamp played an essential role. He conducted many tests to research the interplay of light and sound, experimented with all kinds of incandescent lamps in relation to various light-controlling devices and used many different types of microphones and pickups to "eavesdrop" into the acoustic potential of the various light events.

The result of this research is Glühlampenmusik (Light Bulb Music), an electro-acoustic and audio-visual performance where sounds are generated through the use of different light bulbs and actuating electric devices. The incorporation of different analog light controllers such as switches, dimmers, relays, flashers and various others leads to diverse variations within the light event, made audible with the help of various microphones and pickups. The changes in the light intensity, the incandescence of the filaments and the rhythmic variety of the flickering and pulsing lights is directly transformed into a comprehensive and microcosmic electro-acoustic world of sound. First performed publicly under the title Glühlampenmusikin the Labor Sonor series at Kule, Berlin in January 2005, and released in 2010, this new volume of Glühlampenmusik celebrates its 20th of these sonic adventures that can range from sparse abstractionism to almost "clubby" pulsations.
