One of the weirdest pop/rock groups of the 70s was White Noise. I remember buying Black Mass: An Electric Storm and pretty much wore the grooves off it in the first 6 months. It was typically European in its taste unlike, say, Captain Beefheart who could only be from America. another group I liked a lot were the Residents from San Francisco. All the Ralph Records groups were great like Chrome and Tuxedo Moon. Yello got their start on Ralph Records.
