Oeldorf Group

It consists of a series of eight short pieces for four instrumentalists (clarinet, violin, cello, electric organ/synthesizer) and tape, which may be played either simultaneously or continuously without a break.

The 1973 summer season consisted of three concerts, the last of which took place on 23 June and consisted entirely of premieres of new compositions: David C. Johnson's Progranca—ein Oeldœuvre, Ulrich Stranz's Déja-vue, Silvio Fortić's Drei Lieder aus dem unvollendeten und unvollendbaren Zyklus 'la merde de siècle', and Emmanuel Nunes's The Blending Season.

[9] In 1978 the group joined with the British Hydra Ensemble to inaugurate the newly built hall of the London Goethe Institute in a week of concerts and seminars organised by Rolf Gehlhaar.

In the 1973 summer series, Australian dancer Philippa Cullen (who had come to Germany to work with Karlheinz Stockhausen, who lived nearby) performed with a Theremin connected to a synthesizer, and the Slovenian violinist Miha Pogačnik played Bach's partitas for solo violin.

[5][12] Clarinetists Walter Seyfarth, David Smeyers, Suzanne Stephens, and Beate Zelinsky appeared at various times, and Stockhausen performed in his own composition Herbstmusik, which was written for the group in 1974.
