Black Mist is a collection of Japanese influenced stories and Strangeness is another collection of various strange stories by genre & non genre writers like Shirley Jackson, Virginia Woolf & Thomas Mann. It is edited by Thomas Disch & Charles Naylor.
John Brunner's Stand on Zanzibar and The Sheep Look Up were very popular back in the 1970s though you hardly hear of them these days. He also wrote The Traveller in Black stories which were collected into one volume in 1987.
