I would recommend first two
Die Krupps albums:
Stahlwerksinfonie and
Volle Kraft voraus. The first one consists of two long, noisy post-punk tracks, and the second one is more on the EBM side.
YouTube - ‪Die Krupps -- Stahlwerksinfonie A‬‏
YouTube - ‪Die Krupps - Goldfinger (Long Version)‬‏
Der Plan is quirky minimal synth formed by Pyrolator who was briefly in D.A.F. I recommend their 1980. album
Geri Reig:
YouTube - ‪Der Plan - Adrenalin.mov‬‏
Pyrolator whom I already mentioned.
Inland is a really good album, electronic and more abstract
YouTube - ‪Pyrolator - It Always Rains In Wuppertal‬‏
Liaisons Dangereuses, electro-industrial or EBM, self titled album
YouTube - ‪Liaisons Dangereuses - Los Ninos Del Parque‬‏
Malaria!, album
Emotion
YouTube - ‪malaria!-gewissen‬‏
Palais Schaumburg, self titled, post-punk
YouTube - ‪Palais Schaumburg - Madonna‬‏
That's on top of my head and for now.I will not merge this with recommendation thread, cause it can stand on its own and I really think such exciting and fertile scene like German New Wave deserves a thread. Probably the most influential scene in Europe (outside of UK) in the new wave and post-punk time.
Moved to the punk forum. (Hmmm..maybe we need post-punk sub forum...)
