In a word, outstanding. This is real electronic music. Something designed to transform you mind into another sonic world. I have listed to Rubycon, Phaedra, Socerer and Zeit and Zeit stands out as the most courageous of the works I have heard of Tangerine Dream. I think even Tangerine dream at times tries to find some happy medium between experimenting and trying to market to a more mainstream group of listeners. This is music worthy of being placed in with the more serious, classical, art music side of electronic music.
A short note here to make it clear, as I have in the past, that I am opposed to drugs in any form which the liner note mentions. I understand that a certain ignorant segment of society that feels that need to take drugs to expand their mind. Zeit will take the mind to new places without any drugs at all! Zeit creates an atmosphere, like curtains or rain, Zeit creates textures which morph and blend and come together in this wonderful collage of sounds.
I want to learn more about Zeit. I wish there was more out there because this album first came out in 72 and these sounds are outstanding. No doubt a Moog modular would have been a big part of it but I would love to produce some of these sounds. Many sounds I hear in electronic music are cliched. I can identify who someone created them. These sounds are organic and delightfully electronic. They definitely take the mind to another place.
More later. I have listened to this album about 3 times now and I am not even close to hearing it enough. It gets 11 from me.
