I've read several PKD books and love him as an author. But as the supply of new PKD content runs low, I want to find others authors out there like him. Any suggestions?
Dick's main period of output was the 50s and 60s. I got onto him in the early 70s and for some time found him little different from other authors - in time I latched onto his different phases. Philip E High's works were not dissimilar, content wise to his early novels. When Dick started writing, few SF authors had the luxury of an agent or a book deal - this was back in the early 50s - so short stories were the way to the market. Much of Dick's early fiction was short and a good selection of what he was up against was collected / edited by Kingsley Amis & Robert Conquest in Spectrum I through to V. These are well worth a read as they give a good idea of where the genre was back then - and don't skip their introductions.
The explosion of
New Wave onto the scene emboldened some to experiment. In principle, Harlan Ellison's Dangerous Visions is an exploration of new writings from existing and new authors at the time and I would recommend it as a taster for what was on offer.
Individual titles that might be worth dipping into:
Michael Moorcock:
The Black Corridor (Moorcock sang Dick's praises but imo this is his only work remotely similar)
JG Ballard:
The Terminal Beach, The Drought (or anything by Ballard brefore Crash which borders on torture porn)
John Christopher:
The World in Winter, Pendulum (underated British writer)
DG Compton:
Farewell, Earth's Bliss
Edmund Cooper:
The Overman Culture, Sea-horse in the Sky (Cooper is underrated)
Brian Aldiss:
Barefoot in the Head, Report on Probability A (Barefoot is of its time, Probability is still unfinished imo)
Samuel R Delany:
Dhalgren (I didn't finish this and preferred his inter-galactic stuff tbh)
Mark S Geston:
Lords of the Starship
Maybe worth a look: Vincent King, Barry N Malzberg, Keith Roberts, John Sladek and early Ian Watson.
