1) Necronomicon were formed in 1971 in Aachen, the Western part of Germany near the Belgium and Netherlands border. With an album title (Tips zum Selbtsmord) that means "How to Commit Suicide," Necronomicon's one album, from 1972, featured bleak progressive garage rock with long instrumental passages. With wailing acid guitar solos, dark organ swirls, and angst-ridden singing in German, Necronomicon has created a dark and powerful vision that blends psychedelic and progressive music with a proto-punk garage band sensibility.
