Hanging out in the Peterskirchen artist colony, which was founded by performance artist Fritz Schranz, the Anima-Sound duo of Limpe and Paul Fuchs were well-placed to explore their open, relaxed form of free improvisation. Because they were in Germany, during the 1970s, and had records released on labels like Ohr, they were lumped in with the Krautrock scene, with which they really only had tenuous aesthetic connections, though Stürmischer Himmel certainly shares a spaciousness and exploratory vim with the more open-minded German groups of the time. But Anima-Sound is more reduced, more home-built; Limpe Fuchs’s percussion rambles and trills, while her vocal extemporisations dip and weave between the tones laid out by husband Paul’s invented instruments, all breathy wind and twanging strings.
