Interference is a piece about different rhythmical structures controlling each other. Christinas recordings of electromagnetic waves of all kinds such as security barriers, light advertisings and server rooms from Bangkok to NYC, from Berlin to Shanghai are ruling over the drums in the first part, while the old dependency on metronomic forms is questioned in the second part and develops into a revolutionary reversion of the roles in the third and last part: no longer does the playback track control the drummer, no longer is the machine setting the mood.

A human timing is re-established, the computer seems to become a band member that is listening and adapting, and while Christina is detecting electromagnetic fields live on stage with her specially developed technology that translates electromagnetic waves into audio waves, Katharina is bending the possibilities of following and being followed by BeatSeeker.
