We've talked about Harlan Ellison's I Have No Mouth And I Must Scream before on Extra Sci Fi, but Dangerous Visions is the title that truly kicks off the New Wave. An anthology helmed and edited by Ellison, Dangerous Visions featured short stories written by many sci-fi household names like Roger Zelazny & Samuel R. Delany. But most importantly, it introduced human sexuality to sci-fi in a way we hadn't seen before. It also questioned the taboo, like addressing religion or death. Not all of the stories are winners, but all of them give you something to think about.
