These tracks were all released in an earlier stage. I only own this Der Zyklus record and the Biometry album. So this is the only record which contains the early sound of Der Zyklus.

A1 Mxyzptik is the first track on this record, not very special but an OK track overall.
A2 Der Tonimpulstest is an terrific track in my opinion, electro as it is supposed to be. Braincracking sounds, with a dark feel to it.
B1 Formenverwandler is just amazing. This one sounds sounds like an Other People Place track to me. A warm moody vibe with incredible depth and ongoing rhythm, just magical composed. In my opinion Formenverwandler is classic. It also contains a vocal 'I'm shapeshifting from place to place, bending time, curving space'.
B2 Die Dämmerung Von Nanotech is a great, rather short, track to close down this outstanding record.
