No Secrets in the Family were a Swiss avant-prog band active during the late 1980's and early 1990's. They were heavily influenced by many of the RIO-related bands, in particular the more song-orientated groups like Art Bears, Slapp Happy, Etron Fou Leloublan and News From Babel. The result, as fans of these bands might expect, is playful, quirky art rock which balances discordant elements with melodic touches and places an emphasis on theatrical vocals and complex instrumental interplay. The core group consisted of Annette and Markus Schönholzer who played keys and guitar respectively and shared the main vocal duties, Christian Strässle on violin and saxophone, Daniel Meisenberger on bass and Martin Gantenbein on drums and flute.
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.
