For a long time I thought Tangerine Dream was one of the most boring bands in the world. Until I heard the stuff the Berlin-based band did before they specialized in endless sequencer symphonies.
Their albums Zeit (1972) and Atem (1973) are different. Both contain dark and menacing, ambient drone music, created with electronics but also with organs, cellos, guitars and other instruments. Haunting, unpredictable and only describable as undescribable.
These albums are actually much more powerful than the esoteric soundscape of Phaedra which followed Atem and became the blueprint of their later work.
