Today I stumbled upon http://www.holgerhiller.com, the site of (you guessed it..) Holger Hiller.
I have followed Holger Hiller’s work from his days with the ground breaking “‘Neue Welle” band Palais Schaumburg in the early ’80s:

His debut solo album “Ein Bündel Fäulnis in der Grube” and especially his second album “Oben im Eck” belong to my favorite albums of all time.
They too were ground breaking, this time in the creative use of sampling to create whirling idiosyncratic songs and compositions.

In these Biography of A Song video’s some of the magic behind the  “Oben im Eck” album is explained by Holger Hiller :

However, after the self entitled “”Holger Hiller” album in 2000, nothing was heard anymore of Holger Hiller. According to the bio on his site, he was “going through (a) financial and personal crisis” from 2001 to 2009 and had a long creative break.

Now he seems to be composing again, this time in a collaboration with well known German painter Albert Oehlen, another survivor from the ’80s.
See the page “Joint works with Albert Oehlen” in the News section of his site. The works consist of nine single-edition prints by Albert Oehlen, each juxtaposed and framed with a vinyl record of material specially composed by Hiller. This material is instantly recognizable as Holger Hiller “samplism” if you play the excerpts on the page. A complete recording of the 9 compositions doesn’t seem to be available online or offline. Maybe Hiller’s old record company Mute can release this new stuff, please?
