Since about 1990 Thomas Lehn's central artistical work is live-electronic music, created on the basis of analogue sound synthesis. After a period of working with the Robert Moog's minimoog synthesizer, since 1994 his main electronic equipment is the Synthi A modular analogue synthesizer combined with the DK-2 keyboard, both developed and produced by the British company EMS in the late 1960ies. Thomas Lehn's electronic music is instrumentally live-performed. Musical material, process and structure are created and performed in real time.
