Christopher Priest, an author I have huge respect for, author of such goodness as The Prestige, The Glamour, and The Separation, discusses his top ten Slipstream novels.
"Slipstream does not define a category, but suggests an approach, an attitude, an interest or obsession with thinking the unthinkable or doing the undoable. Slipstream can be visionary, unreliable, odd or metaphysical. It's not magical realism: it's a larger concept that contains magical realism. Some familiar recent slipstream examples: Margaret Atwood's novel The Handmaid's Tale, the films Memento or Being John Malkovich, the opera Jerry Springer. Other novelists who have from time to time carried the slipstream torch include Anthony Burgess, Haruki Murakami, Don DeLillo, Gabriel Garcia Marquez, John Banville, John Fowles, Paul Auster and Dino Buzatti."
