[CP 000.38 CD] Klaus Cornell, Open Music Group; Oratorio Spelaeologico, «Bericht Von Den Beatushöhlen», Die Spiegel
This was the 38th in the "Proto Creel Pone" series, offering both of the LPs initially issued by Jecklin Disco (incidentally the label of the similarly-named musical instrument store & namesake of the "Jecklin Disc" recording method) covering the work of Swiss composer Klaus Cornell & his Open Music Group.
Notable for including "Cottonwood Hill" -era Brainticket member Willy Bischoff (credited here on "Keyboards" but in fact utilizing an entire Live-Electronic setup; his presence echoing Conny Plank's on the Wired LP of the DG "Free Improvisation" box, [CP 000.25 CD]), across a series of performances given between 1972 & 1979 the Group veer between guided improvisations and Kagel/Lachenmann -esque extended techniques with a palpable sense of ease, culminating in the hybrid acoustic-electronic splendor of "Die Spiegel, Kantate Für Soli, Chor, Instrumente Und Live-Elektronik".
Wonderful music, seldom talked about, and fitting neatly within the continuum of Live-Electronic improv mapped out by MEV, Il Gruppo, and the like. Comes as two discs (each clocking in close to an hour) sandwiched inside a six-panel full-color booklet.
