When Ernst Helmuth Flammer uses electronics in his works, he attaches great importance to using material recorded by musicians as the sound source material. He calls the result of this renunciation of synthetically generated sounds "breathing electronics". Most of the works could also be realised with live electronics, which is what happened with some of them. However, Flammer appreciates working in the studio, as it ultimately offers him as a composer more control over the sonic result, which is why the use of live electronics was dispensed with for re-performances as well as for the recordings.

Thus, here are three works for solo instrument with feed, all written in the 1990s, two of them for the violist Marurizio Barbetti: nach vorn II ... (forwards II) and dikursiv - mit drängender Entgegnung (discursive - with urgent rebuttal), the latter also using exclusively viola sounds as source material for the electronics. Panoptikum - ein Klangmobil (Panopticum - a Sound Mobile) for soprano saxophone and 4-channel tape was originally conceived as a performance at the Salzburg Festival; the studio or concert version was created later and was specially recorded by Simone Ehinger for the present edition.
