Flow My Tears, the Policeman Said is a 1974 science fiction novel by American writer Philip K. Dick. The story follows a genetically enhanced pop singer and television star who wakes up in a world where he has never existed. The novel is set in a futuristic dystopia, where the United States has become a police state in the aftermath of a Second Civil War. It was nominated for a Nebula Award in 1974 and a Hugo Award in 1975, and was awarded the John W. Campbell Memorial Award for Best Science Fiction Novel in 1975. TV star Jason Taverner is no more. Overnight, he looses his ID cards, the records about him in the official databases have strangely vanished and no one seems to know him any more. Even the songs he recorded don’t exist any more. In an oppressing police state, Jason struggels not to get arrested.
Philip K. Dick: Ubik, Flow My Tears The Policeman Said, A Scanner Darkly, etc. too many to count (many more than twice)
William Gibson: everything at least twice
Neal Stephenson: Snow crash (three times, I think)
Clifford D. Simak: City
H. P. Lovecraft: everything at least twice. There is a French compilation of The Dream-Quest of Unknown Kadath, The Silver Key, and Through the Gates of the Silver Key that I've read countless times. I've used two editions and I'm at my third.
Maurice G. Dantec: Babylon Babies (three times)
Possibly many others.
Philip K. Dick's Ubik, A Scanner Darkly, and Flow My Tears, The Policeman Said.
Clifford D. Simak's City.
Classics.
It sets up the narrative style and loads the gun for a incoming tragedy.

I quite like to recommend “A Maze Of Death” as a starter, and the short story collections.
There are some very weird (and IMHO great) concept novels like “Flow My Tears the Policeman Said”.
And of course there’s “A Scanner Darkly”
After a while you get a feeling there’s a sort of semi-coherent PKD reality out there, in which continuity is less important than the concept being played with, but the background is consistent in its own odd way.
I do think PKD improved as a writer in the 1970s, once he kicked his drug habit and slowed down his hyperactive output; from this era, Flow My Tears the Policeman Said, A Scanner Darkly, and the VALIS trilogy all has some beautiful writing and show Dick as a deeper and more mature writer.
As for the rest of the sci-fi genre, there's a lot of talent among his contemporaries. I would especially suggest:
* John Crowley. Widely recognized as actual an Author of real Literature, though only his earliest works could be called science fiction. Start with The Deep and Engine Summer.
* Harlan Ellison. Some of his stories ("I Have No Mouth and I Must Scream", "Jeffty Is Five", etc.) are simply masterfully written.
* Samuel Delaney. He's an acquired taste and certainly gets a bit self-indulgent, but novels like Babel 17 are often beautifully written.
* Ursula LeGuin, e.g. The Left Hand of Darkness.
* Gene Wolfe. Increasingly also recognized as a genius, I also particularly like his short stories. Start with The Fifth Head of Cerberus; graduate with the monumental The Book of the New Sun, which has no equal in or out of the genre.
* J. G. Ballard. A consummate stylist, he eventually drifted away from SF, but his earlic works are fantastic. My favourite is The Crystal World, as well as his numerious short stories, including one of my favourite stories ever [1]).
Of later writers, William Gibson, China Mieville and Iain M. Banks come to mind.
