A  group of stu­dents of the MA Sound Stud­ies per­form a rein­ter­pre­ta­tion of  ‘Kurzwellen’, Stock­hausen’s com­po­si­tion dat­ed 1968 and based on the pecu­liar sound char­ac­ter­is­tics of short-wave radios.Four musi­cians, each equipped with an instru­ment and a specif­i­cal­ly designed short-wave sim­u­la­tor, engage in an intri­cate col­lec­tive per­for­mance, imi­tat­ing and trans­form­ing each oth­ers out­put in a process of impro­vised musi­cal meta­mor­pho­sis. At the same time a fifth per­former takes care of the fil­ter­ing and posi­tion­ing of the sounds over 8 speak­ers, cir­cu­lar­ly dis­posed in the room.The impro­vi­sa­tion­al char­ac­ter of the piece gen­er­ates every time a new out­come, fol­low­ing the com­posers nota­tion yet ulti­mate­ly rais­ing from the con­nec­tions between the mem­bers of the ensemble.

The Japan­ese com­pos­er Toshi Ichiyana­gi played an impor­tant role in the New York avant-garde scene in the late 50s. He was con­nect­ed to John Cage and con­sid­ered as a “men­tor” to the Fluxus move­ment. His piece “Appear­ance” (1967) is a com­po­si­tion for instru­ments, oscil­la­tors and ring mod­u­la­tors. It is rep­re­sen­ta­tive for Ichiyanagis idea of “live-elec­tron­ic-music” and based on an inter­ac­tion­al struc­ture for the play­ers with­out leav­ing aside the fac­tor of unpre­dictabil­i­ty. Since hear­ing is pre­ferred to express­ing by Ichiyana­gi, impro­vi­sa­tion has to be start­ed with care­ful hear­ing of the space. Some free­dom has been tak­en regard­ing the instru­men­ta­tion. One of the major dif­fer­ences with the his­tor­i­cal ver­sions is that the ring mod­u­la­tors are emu­lat­ed in a dig­i­tal way thanks to a max-patch. Also, one of the ver­sions will be played with a sax­o­phone and a Shrutibox.

The piece will be per­formed twice, by two dif­fer­ent groups with a slight­ly dif­fer­ent instrumentation.
