Since January 2007 the Stockhausen-Verlag is releasing Text-CDs of a new series: lectures which Stockhausen has given since 1952. The edition is limited to 300 copies per release. He wrote and spoke these lectures in German. Most of them are supplemented with musical examples.
Since 1991, a complete edition of all recordings in which Karlheinz Stockhausen has personally participated is being released on compact discs. Each CD in this series is identified by Stockhausen's signature followed by an encircled number. The numbers indicate the general historical order of the works. Stockhausen realised the electronic music and participated in these recordings as conductor, performer, sound projectionist, and musical director. He personally mixed down the recordings, mastered them for CDs, wrote the texts and drew the covers.
Samstag is an opera for 13 solo performers (1 voice, 10 instrumentalists, and 2 dancers) plus a symphonic band (or symphony orchestra), ballet or mimes, and male choir with organ. It was composed between 1981 and 1983. Saturday is Lucifer's day. It opens with the Samstags Gruss (Saturday's Greeting) for four spatially separated brass ensembles with percussion (Bandur 1999). The opera itself consists of four scenes: Luzifers Traum (Lucifer's Dream), for bass voice and piano; Kathinkas Gesang als Luzifers Requiem (Kathinka's Chant as Lucifer's Requiem), for flute and six perdussionists; Luzifers Tanz (Lucifer's Dance), for symphony band (or orchestra), bass voice, solo piccolo, solo piccolo trumpet, solo dancer, stilt-dancer, and dancer-mimes; and Luzifers Abschied (Lucifer's Farewell), for male choir, seven trombones, and organ.from Wikipedia
