just one brief clarification , before i move on ..this is neither jazz nor improvised music !.. but it fits in nicely with this wonderful recent Germanic thread.
Wolfgang Fortner was once one of Germany's most influential composers , if for no other reason than having been the teacher of Zimmermann, Henze,keleman Wolfgang Rihm,Zender and Even Naim June Paik.
Born in Leipzig in 1907 , he died in 87. his career and the music itself ,seems with hindsight to follow a familiar trajectory.
and in these relatively later works you can hear a typical Darmstadt style of composition ( the post -serial ,aleatory techniques etc
i wish it were possible to hear much more of Fortner's music , alas this sort of thing is hardly fashionable .
Wergo at one time had at least 4 or 5 lp's of Fortners music in circulation , and at least one of those, which featured a sonata for violin and piano, and Zyklus for cello and piano, made it to CD reissue ...
this one never has ... and not much else seems currently available.
this rip is taken from a late 70's reissue of the original 1967 or 68 lp
i've include photos of the booklet , but NB-all the notes are in German>
