Looking for a book to read? Pretty much everything on this list is worth reading. It's Bruce Sterling's 1988 announcement of the Slipstream Genre.

I'd add Lewis Shiner, John Shirley, Paul DiFillipo, Pat Cadigan, Jeff Noon, Michael Swanwick. But mainly, Lucius Shepherd's entire output (RIP).
I do have a small problem though with the Slipstream genre name. I really like Slipstream. The problem is that what I think of as Slipstream doesn't necessarily match what everyone else thinks it is!
And I think we need a replay of the New Worlds group. Where's 2015's JG Ballard?
