I wasn't familiar with this artist but seeing some of his work now, I think you have matched it very well with this composition. But to me it's more of a soundscape and not necessarily "music". Not my idea of music, at least. It's interesting to hear and I bet it would be incredible to set the mood in some kind of dark, imaginative movie, but in my opinion it doesn't quite stand on its own. It's not something I would want to listen to more than once, although maybe your intention was that listeners look through the artwork while listening, so if it is meant to be like an audio/visual experience, I would say that this is perfectly appropriate as the audio component of that. My preference, however, is to seek out music that does in fact stand on its own...music that calls for my undivided attention.
Auch ich bin ein großer Fan von H.R.Giger - dieser Mann was genauso genial wie Salvador Dali, MC Escher oder Max Ernst. Deine düstere bedrohliche "Musik" passt sehr gut zum CoverDesign (Biomechanische Landschaft von 1977). Das ist genau mein Geschmack!!! *****
