This Klaus Schulze CD is much more difficult to place or describe. Privately I call this one my "debug" music: when I need to solve some problem and want to clear my mind out I put headphones and Trancefer on.
There is very little compromise in this music, no sacrifice to nice melodies or catchy rhythms. It forces you to listen and it is difficult to get bored with.
The first piece, with the Escher-like title "A few minutes after trancefer", is probably the best of the two. It is an unhesitating unfolding of powerful soundlines, crisp drums, and underneath it all the occasional fluttering of a cello. Not friendly, but very overpowering if listened to at high volume. It is hard music.
The second piece "Silent running" is indeed calmer and more paced, but without losing intensity.
The CD is from the vinyl era, so the total running time is shorter than you might wish and certainly shorter than I am used to from Schulze.
But this does not matter. It's like one of those pricy crystals you can buy in certain souvenir shops: intricate, beautiful, cold. I wish I could make music like this.
